1 Features

3 Description

•

Ultra-high precision:

The OPA182, OPA2182, and OPA4182 (OPAx182)

are high-precision operational amplifiers in an

ultra-low noise, fast-settling, zero-drift device that

provides rail-to-rail output operation and features

a unique MUX-friendly architecture and controlled

start-up system. These features and excellent ac

performance, combined with only 0.45 µV of offset

voltage and 0.003 µV/°C of drift over temperature,

– Zero-drift: 0.003 μV/°C

– Ultra-low offset voltage: 4 μV (maximum)

Excellent dc precision:

– CMRR: 168 dB

– Open-loop gain: 170 dB

Low noise:

– e_nat 1 kHz: 5.7 nV/√Hz

– 0.1-Hz to 10-Hz noise: 0.12 µV_PP

Excellent dynamic performance:

– Gain bandwidth: 5 MHz

– Slew rate: 10 V/µs

make the OPAx182

great choice for data

acquisition, battery test, analog input modules, weigh

scales, and any other systems requiring high dc

precision and low noise.

– Fast settling: 10-V step, 0.01% in 1.7 µs

Robust design:

– MUX-friendly inputs

– RFI/EMI filtered inputs

Wide supply: : ±2.25 V to ±18 V, 4.5 V to 36 V

Quiescent current: 0.85 mA

Rail-to-rail output

The MUX-friendly input architecture prevents inrush

current when applying large input differential voltages

that improves settling performance in multichannel

systems. Moreover, the controlled start-up system

rejects any inrush current upon ramping up the supply

rails, all while providing robust ESD protection during

shipment, handling, and assembly.

•

Input includes negative rail

The device is specified from –40°C to +125°C.
