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.
