Single, 40-V 4.5-MHz low-power operational amplifier

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, typical), low offset drift (±0.3 µV/°C, typical),

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 and WSON), as well as standard

packages (such as SOT-23, SOIC, and TSSOP), and is specified from –40°C to 125°C.
