OPA191 Overview
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 bandwidth.
