3 Description
The OPAx991 family (OPA991, OPA2991, and
OPA4991) is a family of high voltage (40-V) general
purpose operational amplifiers. These devices offer
exceptional DC precision and AC performance,
including rail-to-rail input/output, low offset (±125 µV,
typ), low offset drift (±0.3 µV/°C, typ), low noise (10.5
nV/√ Hz and 1.8 µVPP) and 4.5-MHz bandwidth.
Unique features such as differential and common-
mode input-voltage range to the supply rail, high
output current (±75 mA), high slew rate (21 V/µs),
high capacitive load drive (1 nF) and shutdown
functionality make the OPAx991 a robust, high-
performance operational amplifier for high-voltage
industrial applications.
The OPAx991 family of op amps is available in micro-
size packages (such as X2QFN, WSON, and
SOT-553), as well as standard packages (such as
SOT-23, SOIC, and TSSOP), and is specified from –
40°C to 125°C.
