The OPA2990 high voltage (40 V) general purpose op amp offers excellent DC accuracy and AC performance, including rail-to-rail input and output, low offset voltage (±300μV typ), and low offset drift (±0.6μV/°C typ).

The OPA2990 device features differential and common-mode input voltage ranges for the supply rails, high short-circuit current (±80 mA), high slew rate (4.5 V/μs), and shutdown capability for extreme flexibility, robustness, and high performance , suitable for high pressure industrial applications.

The OPA2990 operational amplifier is available in tiny packages (X2QFN, WSON, and SOT-553) and standard packages (SOT-23, SOIC, and TSSOP). These op amps are specified over the temperature range of -40°C to +125°C.
