OPA2991IDR Operational Amplifiers Datasheet

 Product Overview

The OPAx991 family (OPA991, OPA2991, and OPA4991) is a family of high voltage (40 V) general

purpose operational amplifiers. These devices offer exceptional DC precision and AC performance, including rail-to-rail input/output, low offset (±125 µV, typical), low offset drift (±0.3 µV/°C, typical), low noise (10.5 nV/√Hz and 1.8 µVPP), and 4.5-MHz bandwidth.

 

This blog will introduce OPA2991IDR systematically from its features, pinout to its specifications, applications, also including OPA2991IDR datasheet and so much more.
