OPA49PW
Overview
The OPAx990 family (OPA990, OPA2990, and OPA4990) is a family of high voltage (40-V) general purpose operational amplifiers. These devices offer excellent DC precision and AC performance, including rail-to-rail input/output, low offset (±300 µV, typ), and low offset drift (±0.6 µV/°C, typ).
- 1 Low offset voltage: ±300 µV
- Low offset voltage drift: ±0.6 µV/°C
- Low noise: 30 nV/√Hz at 1 kHz
- High common-mode rejection: 115 dB
- Low bias current: ±10 pA
- Rail-to-rail input and output
- MUX-friendly/comparator inputs - Amplifier operates with differential inputs up to supply rail - Amplifier can be used in open-loop or as comparator
- Wide bandwidth: 1.1-MHz GBW
- High slew rate: 4.5 V/µs
- Low quiescent current: 120 µA per amplifier
