3 Description

The OPAx992 family (OPA992, OPA2992, and

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

purpose operational amplifiers. These devices offer

excellent DC precision and AC performance, including

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

offset drift (±0.25 μV/°C, typ) and low noise (7 nV/√Hz

at 1 kHz, 4.4 nV/√Hz at 10 kHz).

Features such as differential and common-mode input

voltage ranges to the supply rails, high short-circuit

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

packages (such as WSON), as well as standard

packages (such as SOT-23, SOIC, and TSSOP), and

is specified from –40°C to 125°C.
