GENERAL DESCRIPTION

The OP400 is the first monolithic quad operational amplifier

that features OP77 type performance. Precision performance no

longer has to be sacrificed to obtain the space and cost savings

offered by quad amplifiers.

The OP400 features low power consumption, drawing less than

725 mA per amplifier. The total current drawn by this quad

amplifier is less than that of a single OP07, yet the OP400 offers

significant improvements over this industry standard op amp.

The OP400 features an extremely low input offset voltage of

less than 150 mV with a drift of under 1.2 mV/∞C, guaranteed

over the full military temperature range. Open-loop gain of the

OP400 is over 5,000,000 into a 10 kW load, input bias current is

under 3 nA, CMR is above 120 dB, and PSRR is below 1.8 mV/V.

On-chip zener-zap trimming is used to achieve the low input

offset voltage of the OP400 and eliminates the need for offset

nulling. The OP400 conforms to the industry-standard quad

pinout which does not have null terminals.

Voltage noise density of the OP400 is a low 11 nV/

which is half that of most competitive devices.

÷Hz at 10 Hz,

The OP400 is pin-compatible with the LM148, HA4741,

RM4156, and LT1014 operational amplifiers and can be used

to upgrade systems using these devices. The OP400 is an ideal

choice for applications requiring multiple precision operational

amplifiers and where low power consumption is critical.

The output signal is specified with respect to the reference

input, which is normally connected to analog ground. The refer-

ence input can be used to offset the output from –10 V to +10 V

if required.

APPLICATIONS INFORMATION

The OP400 is inherently stable at all gains and is capable of

driving large capacitive loads without oscillating. Nonetheless,

good supply decoupling is highly recommended. Proper supply

decoupling reduces problems caused by supply line noise and

improves the capacitive load driving capability of the OP400.

Total supply current can be reduced by connecting the inputs of

an unused amplifier to –V. This turns the amplifier off, lowering

the total supply current.

APPLICATIONS

Dual Low-Power Instrumentation Amplifier

A dual instrumentation amplifier that consumes less than 33 mW

of power per channel is shown in Figure 1. The linearity of the

instrumentation amplifier exceeds 16 bits in gains of 5 to 200

and is better than 14 bits in gains from 200 to 1000. CMRR is

above 115 dB (G = 1000). Offset voltage drift is typically 0.4

mV/∞C over the military temperature range which is comparable

to the best monolithic instrumentation amplifiers. The band-

width of the low-power instrumentation amplifier is a function

of gain and is shown in Table I.

–8–

REV. A

OP400

Figure 5. Bipolar Current Transmitter

BIPOLAR CURRENT TRANSMITTER

In the circuit of Figure 5, which is an extension of the standard

three op amp instrumentation amplifier, the output current is

proportional to the differential input voltage. Maximum output

current is ±5 mA with voltage compliance equal to ±10 V when

using ±15 V supplies. Output impedance of the current transmit-

ter exceeds 3 MW and linearity is better than 16 bits with gain

set for a full scale input of ±100 mV.

DIFFERENTIAL OUTPUT INSTRUMENTATION

AMPLIFIER

The output voltage swing of a single-ended instrumentation

amplifier is limited by the supplies, normally at ±15 V, to a

maximum of 24 V p-p. The differential output instrumentation

amplifier of Figure 6 can provide an output voltage swing of

48 V p-p when operated with ±15 V supplies. The extended

output swing is due to the opposite polarity of the outputs. Both

outputs will swing 24 V p-p but with opposite polarity, for a

total output voltage swing of 48 V p-p. The reference input can

be used to set a common-mode output voltage over the range

±10 V. PSRR of the amplifier is less than 1 mV/V with CMRR

(G = 1000) better than 115 dB. Offset voltage drift is typically

0.4 mV/∞C over the military temperature range.

MULTIPLE OUTPUT TRACKING VOLTAGE

REFERENCE

Figure 7 shows a circuit that provides outputs of 10 V, 7.5 V, 5 V,

and 2.5 V for use as a system voltage reference. Maximum

output current from each reference is 5 mA with load regulation

under 25 mV/mA. Line regulation is better than 15 mV/V and

output voltage drift is under 20 mV/∞C. Output voltage noise

from 0.1 Hz to 10 Hz is typically 75 mV p-p from the 10 V output

and proportionately less from the 7.5 V, 5 V, and 2.5 V outputs.
