The OPA990 is a single, 40V, 1.1MHz, low power operational amplifier

The OPA990 family (OPA990, OPA2990 and OPA4990) is a family of high voltage (40 V) general purpose operational amplifiers. These devices offer excellent DC accuracy and AC performance, including rail-to-rail input/output, low offset (±300 μV, typ), and low offset drift (±0.6 μV/°C, typ).

The unique features of the power rails' differential and common-mode input voltage ranges, high short-circuit current (±80 mA), high slew rate (4.5 V/μs), and shutdown make the OPA990 an extremely flexible, robust, and suitable for high-voltage industrial applications The AP8801SG-13 high performance operational amplifier.

The OPA990 family of op amps is available in tiny packages such as X2QFN, WSON, and SOT-553 as well as standard packages such as SOT-23, SOIC, and TSSOP, and are specified from –40°C to 125°C.
