3 Description
The OPAx991-Q1 family (OPA991-Q1, OPA2991-Q1,
and OPA4991-Q1) is a family of high voltage (40 V)
general purpose operational amplifiers for automotive
application. These devices offer exceptional DC
precision and AC performance, including rail-to-rail
input or output, low offset (±125 μV, typical), low offset
drift (±0.3 μV/°C, typical), low noise (10.8 nV/√Hz and
1.8 μVPP), and 4.5-MHz bandwidth.
Unique features such as differential and commonmode
input-voltage range to the supply rail, high
output current (±75 mA), high slew rate (21 V/μs), and
high capacitive load drive (1 nF) make the OPAx991-
Q1 a robust, high-performance operational amplifier
for high-voltage automotive applications.
The OPAx991-Q1 family of op amps is available in
standard packages (such as SOT-23, SC70, SOIC,
VSSOP, and TSSOP) and is specified from –40°C to
125°C.
