The OPAx992 family (OPA992, OPA2992, and OPA4992) is a family of high voltage (40V) general purpose operational amplifiers. These devices offer excellent DC precision and AC performance, including rail-to-rail input/output, low offset (±210µV, typical), low offset drift (±0.25µV/°C, typical) and low noise (7nV/√Hz at 1kHz, 4.4nV/√Hz at 10kHz).
Features such as differential and common-mode input voltage ranges to the supply rails, high short-circuit current (±65mA), and high slew rate (32V/µs) make the OPAx992 a flexible, robust, and high-performance op amp for high-voltage industrial applications.
The OPAx992 family of op amps is available in small-size packages (such as X2QFN and WSON), as well as standard packages (such as SOT-23, SOIC, and TSSOP), and is specified from –40°C to 125°C.
