OPA171, OPA2171, OPA4171

SBOS516E – SEPTEMBER 2010 – REVISED JUNE 2015

OPAx171 36-V, Single-Supply, SOT553, General-Purpose Operational Amplifiers

1 Features

3 Description

The OPA171, OPA2171, and OPA4171 (OPAx171)

1

•

Supply Range: 2.7 to 36 V, ±1.35 V to ±18 V

are

a

family

of

36-V,

single-supply,

low-noise

•

Low Noise: 14 nV/

√Hz

operational amplifiers with the ability to operate on

•

Low Offset Drift: ±0.3 µV/°C (Typical)

supplies ranging from 2.7 V (±1.35 V) to 36 V (±18

V). These devices are available in micro-packages

•

RFI Filtered Inputs

and offer low offset, drift, and bandwidth with low

•

Input Range Includes the Negative Supply

quiescent

current.

The

single,

dual,

and

quad

•

Input Range Operates to Positive Supply

versions all have identical specifications for maximum

design flexibility.

•

Rail-to-Rail Output

•

Gain Bandwidth: 3 MHz

Unlike

most

operational

amplifiers,

which

are

specified at only one supply voltage, the OPAx171

•

Low Quiescent Current: 475 µA per Amplifier

family is specified from 2.7 to 36 V. Input signals

•

High Common-Mode Rejection: 120 dB (Typical)

beyond the supply rails do not cause phase reversal.

•

Low-Input Bias Current: 8 pA

The OPAx171 family is stable with capacitive loads

•

Industry-Standard Packages:

up to 300 pF. The input can operate 100 mV below

the negative rail and within 2 V of the top rail during

–

8-Pin SOIC

normal operation. These devices can operate with full

–

8-Pin MSOP

rail-to-rail input 100 mV beyond the top rail, but with

–

14-Pin TSSOP

reduced performance within 2 V of the top rail.

•

microPackages:

The OPAx171 series of operational amplifiers are

–

Single in SOT553

specified from –40°C to 125°C.

–

Dual in VSSOP-8
