LOW COST

FET-INPUT OPERATIONAL AMPLIFIERS

™

MicroAmplifier Series

FEATURES

● FET INPUT: I_B= 5pA

● LOW OFFSET VOLTAGE: 1.5mV

● WIDE SUPPLY RANGE: ±2.25V to ±18V

● LOW QUIESCENT CURRENT: 220µA/channel

● EXCELLENT SPEED/POWER: 1MHz

● INPUT TO POSITIVE SUPPLY

DESCRIPTION

OPA137 series FET-input operational amplifiers are designed

for low cost and miniature applications. In addition to small

size (SOT-23-5 and MSOP-8 packages), they provide low

input bias current (5pA), low quiescent currrent (220µA/

channel), and high open-loop gain (94dB).

Either single (+4.5V to +36V) or dual (±2.25 to ±18V)

supplies can be used. The input common-mode voltage range

includes the positive supply—suitable for many single-supply

applications. Single, dual, and quad versions have identical

specifications for maximum design flexibility.

● MicroSIZE PACKAGES: SOT-23-5, MSOP-8

● SINGLE, DUAL, AND QUAD

OPA137 op amps are easy to use and free from phase

inversion and overload problems found in some FET-input

amplifiers. High performance, including linearity, is main-

tained as the amplifiers swing to their specified limits. In

addition, the combination of high slew rate (3.5V/µs) and

wide bandwidth (1MHz) provide fast settling time assuring

good dynamic response. Dual and quad designs feature com-

pletely independent circuitry for lowest crosstalk and freedom

from interaction.

APPLICATIONS

● STRAIN GAGE AMPLIFIER

● PHOTODETECTOR AMPLIFIER

● PRECISION INTEGRATOR

● BATTERY-POWERED INSTRUMENTS

● TEST EQUIPMENT

The single (OPA137) packages are the tiny 5-lead SOT-23-5

surface mount, SO-8 surface mount, and 8-pin DIP. The dual

(OPA2137) comes in the miniature MSOP-8 surface mount,

SO-8 surface mount, and 8-pin DIP packages. The quad

(OPA4137) packages are the SO-14 surface mount and the

14-pin DIP. All are specified from –40°C to +85°C and operate

from –55°C to +125°C. A SPICE macromodel is available for

design analysis.

HIGH-SIDE CURRENT SENSING

APPLICATIONS INFORMATION

Many applications require the sensing of signals near the

positive supply. The common-mode input range of OPA137

op amps includes the positive rail, enabling them to be used

to sense power supply currents as shown in Figure 2.

OPA137 series op amps are unity-gain stable and suitable

for a wide range of general-purpose applications. Power

supply pins should be bypassed with 10nF ceramic capaci-

tors or larger. All circuitry is completely independent in dual

and quad versions, assuring normal performance when one

amplifier in a package is overdriven or short circuited. Many

key parameters are guaranteed over the specified tempera-

ture range, –40°C to +85°C.

OPERATING VOLTAGE

OPA137 op amps can be operated on power supplies as low

as ±2.25V. Performance remains excellent with power sup-

plies ranging from ±2.25V to ±18V (+4.5V to +36V single

supply). Most parameters vary only slightly throughout this

supply voltage range. Quiescent current and short-circuit

current vs supply voltage are shown in Typical Performance

Curves.

Operation at very low supply voltage (V_S≤ ±3V) requires

careful attention to ensure that the common-mode voltage

remains within the linear range, V_CM= (V–)+3V to (V+).

Inputs may need to be biased above ground in accordance

with the common-mode voltage range restrictions for linear

operation.

FIGURE 2. High-Side Current Monitor.

INPUT VOLTAGE

The input common-mode voltage range of OPA137 series

op amps extends from (V–)+3V to the positive rail, V+. For

normal operation, inputs should be limited to this range. The

inputs may go beyond the power supplies without output

phase-reversal. Many FET-input op amps (such as TL061

types) exhibit phase-reversal of the output when the input

common-mode range is exceeded. This can occur in voltage-

follower circuits, causing serious problems in control loop

applications.

INPUT BIAS CURRENT

The input bias current is approximately 5pA at room tem-

perature and increases with temperature as shown in the

typical performance curve “Input Bias Current vs Tempera-

ture.”

Input Bias current also varies with common-mode voltage

and power supply voltage. This variation is dependent on

the voltage between the negative power supply and the

common-mode input voltage. The effect is shown in the

typical performance curve “Input Bias Current vs Common-

Mode Voltage.”

Input terminals are diode-clamped to the power supply rails

for ESD protection. If the input voltage can exceed the

negative supply by 500mV, input current should be limited

to 2mA (or less). If the input current is not adequately

limited, you may see unpredicatable behavior in the other

amplifiers in the package. This is easily accomplished with

an input resistor as shown in Figure 1. Many input signals

are inherently current-limited, therefore, a limiting resistor

may not be required.
