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.
