OPA992IDCKR

The OPAx992 (OPA992, OPA2992, and OPA4992) is a family of high-voltage (40V) general-purpose operational amplifiers. These devices feature excellent DC accuracy and AC performance, including rail-to-rail input/output, low offset voltage (±210 μV, typical), low temperature drift (±0.25 μV/°C, typical), and low noise (7nV/√Hz at 1 kHz and 4.4nV/√Hz at 10 kHz). The OPAx992 offers many features such as differential and common-mode input voltage ranges up to the supply rails, high short-circuit current (±65 mA), and high slew rate (32 V/µs). Therefore, it is a flexible and reliable high-performance operational amplifier suitable for various high-voltage industrial applications. The OPAx992 operational amplifier family is available in miniature packages (e.g., WSON) as well as standard packages (e.g., SOT-23, SOIC, and TSSOP) and is specified for operation from -40°C to 125°C.
