GENERAL DESCRIPTION

NC

The OPx13 family of single-supply operational amplifiers

features both low noise and drift. It has been designed for

systems with internal calibration. Often these processor-based

systems are capable of calibrating corrections for offset and

gain, but they cannot correct for temperature drifts and noise.

Optimized for these parameters, the OPx13 family can be used

to take advantage of superior analog performance combined

with digital correction. Many systems using internal calibration

operate from unipolar supplies, usually either 5 V or 12 V. The

OPx13 family is designed to operate from single supplies from

4 V to 36 V and to maintain its low noise and precision

performance.

Digital scales and other strain gage applications benefit from

the very low noise and low drift of the OPx13 family. Other

applications include use as a buffer or amplifier for both analog-

to-digital (ADC) and digital-to-analog (DAC) sigma-delta

converters. Often these converters have high resolutions

requiring the lowest noise amplifier to utilize their full

potential. Many of these converters operate in either single-

supply or low-supply voltage systems, and attaining the greater

signal swing possible increases system performance.

The OPx13 family is unity gain stable and has a typical gain

bandwidth product of 3.4 MHz. Slew rate is in excess of 1 V/μs.

Noise density is a very low 4.7 nV/√Hz, and noise in the 0.1 Hz

to 10 Hz band is 120 nV p-p. Input offset voltage is guaranteed

and offset drift is guaranteed to be less than 0.8 μV/°C. Input

common-mode range includes the negative supply and to

within 1 V of the positive supply over the full supply range.

Phase reversal protection is designed into the OPx13 family for

cases where input voltage range is exceeded. Output voltage

swings also include the negative supply and go to within 1 V of

the positive rail. The output is capable of sinking and sourcing

current throughout its range and is specified with 600 Ω loads.

The OPx13 family is specified for single 5 V and dual 15 V

operation over the XIND—extended industrial temperature

range (–40°C to +85°C). They are available in PDIP and SOIC

surface-mount packages.

OP113/OP213/OP413

APPLICATIONS

The OP113, OP213, and OP413 form a new family of high

performance amplifiers that feature precision performance in

standard dual-supply configurations and, more importantly,

maintain precision performance when a single power supply is

used. In addition to accurate dc specifications, it is the lowest

noise single-supply amplifier available with only 4.7 nV/√Hz

typical noise density.

PHASE REVERSAL

The OPx13 family is protected against phase reversal as long as

both of the inputs are within the supply ranges. However, if

there is a possibility of either input going below the negative

supply (or ground in the single-supply case), the inputs should

be protected with a series resistor to limit input current to 2 mA.

OP113 OFFSET ADJUST

Single-supply applications have special requirements due to the

generally reduced dynamic range of the output signal. Single-

supply applications are often operated at voltages of 5 V or 12 V,

compared to dual-supply applications with supplies of 12 V or

15 V. This results in reduced output swings. Where a dual-

supply application may often have 20 V of signal output swing,

single-supply applications are limited to, at most, the supply

range and, more commonly, several volts below the supply.

In order to attain the greatest swing, the single-supply output

stage must swing closer to the supply rails than in dual-supply

applications.

The OP113 has the facility for external offset adjustment, using

the industry standard arrangement. Pin 1 and Pin 5 are used in

conjunction with a potentiometer of 10 kΩ total resistance,

connected with the wiper to V− (or ground in single-supply

applications). The total adjustment range is about 2 mV using

this configuration.

Adjusting the offset to 0 has minimal effect on offset drift

(assuming the potentiometer has a tempco of less than

1000 ppm/°C). Adjustment away from 0, however, (as with all

bipolar amplifiers) results in a TCV_OSof approximately

3.3 μV/°C for every millivolt of induced offset.

The OPx13 family has a new patented output stage that allows

the output to swing closer to ground, or the negative supply,

than previous bipolar output stages. Previous op amps had

outputs that could swing to within about 10 mV of the negative

supply in single-supply applications. However, the OPx13

family combines both a bipolar and a CMOS device in the output

stage, enabling it to swing to within a few hundred ꢀV of ground.

It is, therefore, not generally recommended that this trim be

used to compensate for system errors originating outside of the

OP113. The initial offset of the OP113 is low enough that

external trimming is almost never required, but if necessary, the

2 mV trim range may be somewhat excessive. Reducing the

trimming potentiometer to a 2 kΩ value results in a more

reasonable range of 400 μV.

When operating with reduced supply voltages, the input range

is also reduced. This reduction in signal range results in

reduced signal-to-noise ratio for any given amplifier. There are

only two ways to improve this: increase the signal range or

reduce the noise. The OPx13 family addresses both of these

parameters. Input signal range is from the negative supply to

within 1 V of the positive supply over the full supply range.

Competitive parts have input ranges that are 0.5 V to 5 V less

than this. Noise has also been optimized in the OPx13 family.

At 4.7 nV/√Hz, the noise is less than one fourth that of competitive

devices.

The OPx13 family makes an excellent amplifier for

conditioning a load-cell bridge. Its low noise greatly improves

the signal resolution, allowing the load cell to operate with a

smaller output range, thus reducing its nonlinearity. Figure 41

shows one half of the OPx13 family used to generate a very

stable 10 V bridge excitation voltage while the second amplifier

provides a differential gain. R4 should be trimmed for

maximum common-mode rejection.

OUTPUT

Zero suppressing the bridge facilitates simple linearization of

the resistor temperature device (RTD) by feeding back a small

amount of the output signal to the RTD. In Figure 43, the left

leg of the bridge is servoed to a virtual ground voltage by

Amplifier A1, and the right leg of the bridge is servoed to 0 V

by Amplifier A2. This eliminates any error resulting from

common-mode voltage change in the amplifier. A 3-wire RTD

is used to balance the wire resistance on both legs of the bridge,

thereby reducing temperature mismatch errors. The 5 V bridge

excitation is derived from the extremely stable AD588 reference

device with 1.5 ppm/°C drift performance.

A LOW VOLTAGE, SINGLE SUPPLY STRAIN GAGE

AMPLIFIER

The true zero swing capability of the OPx13 family allows the

amplifier in Figure 42 to amplify the strain gage bridge

accurately even with no signal input while being powered by a

single 5 V supply. A stable 4 V bridge voltage is made possible

by the rail-to-rail OP295 amplifier, whose output can swing to

within a millivolt of either rail. This high voltage swing greatly

increases the bridge output signal without a corresponding

increase in bridge input.

Linearization of the RTD is done by feeding a fraction of the

output voltage back to the RTD in the form of a current. With

just the right amount of positive feedback, the amplifier output

will be linearly proportional to the temperature of the RTD.

Figure 43. Ultraprecision RTD Amplifier

Extremely low noise instrumentation amplifiers can be built

using the OPx13 family. Such an amplifier that operates from a

single supply is shown in Figure 45. Resistors R1 to R5 should

be of high precision and low drift type to maximize CMRR

performance. Although the two inputs are capable of operating

to 0 V, the gain of −100 configuration limits the amplifier input

common-mode voltage to 0.33 V.

To calibrate the circuit, first immerse the RTD in a 0°C ice bath

or substitute an exact 100 Ω resistor in place of the RTD. Adjust

the zero adjust potentiometer for a 0 V output, and then set R9,

linearity adjust potentiometer, to the middle of its adjustment

range. Substitute a 280.9 Ω resistor (equivalent to 500°C) in

place of the RTD, and adjust the full-scale adjust potentiometer

for a full-scale voltage of 5 V.

5V TO 36V

To calibrate out the nonlinearity, substitute a 194.07 Ω resistor

(equivalent to 250°C) in place of the RTD, and then adjust the

linearity adjust potentiometer for a 2.5 V output. Check and

readjust the full-scale and half-scale as needed.

Figure 45. Ultralow Noise, Single Supply Instrumentation Amplifier

Figure 44 shows a popular K-type thermocouple amplifier with

cold-junction compensation. Operating from a single 12 V

supply, the OPx13 family’s low noise allows temperature

measurement to better than 0.02°C resolution over a 0°C to

1000°C range. The cold-junction error is corrected by using an

inexpensive silicon diode as a temperature measuring device.

It should be placed as close to the two terminating junctions as

physically possible. An aluminum block might serve well as an

isothermal system.

SUPPLY SPLITTER CIRCUIT

The OPx13 family has excellent frequency response

characteristics that make it an ideal pseudoground reference

generator, as shown in Figure 46. The OPx13 family serves as a

voltage follower buffer. In addition, it drives a large capacitor

that serves as a charge reservoir to minimize transient load

changes, as well as a low impedance output device at high

frequencies. The circuit easily supplies 25 mA load current with

good settling characteristics.

The OPx13 family’s low noise and single supply capability are

ideally suited for stereo DAC audio reproduction or sound

synthesis applications such as multimedia systems. Figure 48

shows an 18-bit stereo DAC output setup that is powered from a

single 5 V supply. The low noise preserves the 18-bit dynamic

range of the AD1868. For DACs that operate on dual supplies,

the OPx13 family can also be powered from the same supplies.

LOW NOISE VOLTAGE REFERENCE

Few reference devices combine low noise and high output drive

capabilities. Figure 47 shows the OPx13 family used as a two-

pole active filter that band limits the noise of the 2.5 V reference.

Total noise measures 3 μV p-p.

With its PNP inputs and 0 V common-mode capability, the

OPx13 family can make useful voltage comparators. There is

only a slight penalty in speed in comparison to IC comparators.

However, the significant advantage is its voltage accuracy. For

example, V_OScan be a few hundred microvolts or less, combined

with CMRR and PSRR exceeding 100 dB, while operating from

a 5 V supply. Standard comparators like the 111/311 family

operate on 5 V, but not with common mode at ground, nor with

offset below 3 mV. Indeed, no commercially available single-

supply comparator has a V_OSless than 200 μV.

Figure 51 shows the OPx13 family response to a 10 mV

overdrive signal when operating in open loop. The top trace

shows the output rising edge has a 15 μs propagation delay,

whereas the bottom trace shows a 7 μs delay on the output

falling edge. This ac response is quite acceptable in many

applications.

The low noise and 250 μV (maximum) offset voltage enhance

the overall dc accuracy of this type of comparator. Note that zero-

crossing detectors and similar ground referred comparisons can be

implemented even if the input swings to −0.3 V below ground.
