OPA191 Datasheet - Texas Instruments

OPA191 Low Input Bias Current Op Amp

The OPAx191 family (OPA191, OPA2191, and OPA4191) is a new generation of 36-V, e-trim™ operational amplifiers. These devices offer outstanding dc precision and ac performance, including rail-to-rail input/output, low offset voltage (±5 µV, typ), low offset drift (±0.2 µV/°C, typ), and 2-MHz bandwidt.

OPA191 Features

* 1 Low offset voltage: ±5 µV

* Low offset voltage drift: ±0.1 µV/°C

* Low noise: 15 nV/√Hz at 1 kHz

* High common-mode rejection: 140 dB

* Low bias current: ±5 pA

* Rail-to-rail input and output

* Wide bandwidth: 2.5-MHz GBW

* High slew
