These devices offer excellent DC precision and AC performance, including rail-to-rail input or output, low offset (±210 µV, typical), low offset drift (±0.25 µV/°C, typical) 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-Q1 a flexible, robust, and high- performance op amp for high-voltage automotive applications. The OPAx992-Q1 family of op amps is available in standard packages (such as SOIC, TSSOP, VSSOP, SOT-23, and SC70), and is specified from –40°C to 125°C.
