3 Description

The OPAx992-Q1 family (OPA992-Q1, OPA2992-Q1,

and OPA4992-Q1) 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 or 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 shortcircuit

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

make the OPAx992-Q1 a flexible, robust, and highperformance

op amp for high-voltage automotive

applications.

The OPAx992-Q1 family of op amps is available in

standard packages (such as SOIC, TSSOP, VSSOP,

SOT-23, and SC70), and is specified from –40°C to

125°C.
