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, 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 commonmode 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, highperformance operational amplifier for high-voltage industrial applications.
