描述 Description

The OPAx992 family (OPA992, OPA2992, and OPA4992) is a family of high voltage (40 V) general purpose operational amplifiers. These devices offer excellent DC precision and AC performance, including rail-to-rail input/output, low offset (±210 µV, typ), low offset drift (±0.25 µV/°C, typ) and low noise (7 nV/√Hz at 1 kHz, 4.4 nV/√Hz at 10 kHz).

Features such as differential and common-mode input voltage ranges to the supply rails, high short-circuit current (±65 mA), and high slew rate (32 V/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 micro-size packages (such as WSON), as well as standard packages (such as SOT-23, SOIC, and TSSOP), and is specified from –40°C to 125°C.
