OPA4990 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). Unique
OPA4990 Key Features
- Low offset voltage: ±300 µV - Low offset voltage drift: ±0.6 µV/°C - Low noise: 30 nV/√Hz at 1 kHz - High mon-mode rejec
- Amplifier operates with differential inputs up to supply rail
- Amplifier can be used in open-loop or as parator
OPA4990 Applications
- Multiplexed data-acquisition systems - Test and measurement equipment - Motor drive: power stage and control modules - P
