3 Description

The OPAx992 family (OPA992, OPA2992, and

OPA4992) is a family of high voltage (40V) general

purpose operational amplifiers. These devices offer

excellent DC precision and AC performance, including

rail-to-rail input/output, low offset (±210μV, typical),

low offset drift (±0.25μV/°C, typical) and low noise

(7nV/√Hz at 1kHz, 4.4nV/√Hz at 10kHz).

Features such as differential and common-mode input

voltage ranges to the supply rails, high short-circuit

current (±65mA), and high slew rate (32V/μs) make

the OPAx992 a flexible, robust, and high-performance

op amp for high-voltage industrial applications.

The OPAx992 family of op amps is available in smallsize

packages (such as X2QFN and WSON), as well

as standard packages (such as SOT-23, SOIC, and

TSSOP), and is specified from –40°C to 125°C.
