OPA2990 Low-Power Op-Amp
Texas Instruments' rail-to-rail input/output op-amps are ideal for applications such as motor drives and power delivery
Texas Instruments' OPA2990 high-voltage (40 V) general purpose op-amps offer excellent DC precision and AC performance including rail-to-rail input and output, low offset (±300 µV, typical), and low offset drift (±0.6 µV/°C, typical).
The OPA2990 devices feature 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 making them extremely flexible, robust, and high-performing for high-voltage industrial applications.
The OPA2990 op-amps are available in micro-size packages (X2QFN, WSON, and SOT-553) and standard packages (SOT-23, SOIC, and TSSOP). The op-amp devices are specified from -40°C to +125°C.
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
- MUX-friendly/comparator inputs:
- Amp operates with differential inputs up to the supply rail
- Amp can be used in open-loop or as a comparator
- Low bias current: ±20 pA
- Rail-to-rail input/output
- Wide bandwidth: 1.1 MHz GBW
- High slew rate: 4.5 V/µs
- Low quiescent current: 120 µA per amp
- 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 the supply rail
Applications
