1 / 81 page  OPAx990 40-V Rail-to-Rail Input/Output, Low Offset Voltage, Low Power Op Amp 1 Features • 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 • Wide supply: ±1.35 V to ±20 V, 2.7 V to 40 V • Robust EMIRR performance: 78 dB at 1.8 GHz • Differential and common-mode input voltage range to supply rail 2 Applications • Multiplexed data-acquisition systems • Test and measurement equipment • Motor drive: power stage and control modules • Power delivery: UPS, server, and merchant network power • ADC driver and reference buffer amplifier • Programmable logic controllers • Analog input and output modules • High-side and low-side current sensing • High precision comparator 3 Description 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 features such as differential and common- mode input voltage range to the supply rail, high short-circuit current (±80 mA), high slew rate (4.5 V/ µs), and shutdown make the OPAx990 an extremely flexible, robust, and high-performance op amp for high-voltage industrial applications. The OPAx990 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.
