3 Description

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

and OPA4992-Q1) 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-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.
