MCP621ST-E/OT

MCP621ST-E/OT is a high bandwidth and high slew rate operational amplifier that features low offset. At power-up, this op-amp is self-calibrated using mCal. Some package options also provide a Calibration /Chip Select pin (CAL/active-low CS) that supports a Low-Power mode of operation, with offset calibration at the time normal operation is re-started. This amplifier is optimized for high speed, low noise and distortion, single-supply operation with rail-to-rail output and an input that includes the negative rail. Typical application includes optical detector amplifier, barcode scanners, multi-pole active filter, driving A/D converters, fast low-side current sensing, power amplifier control loops, consumer audio.
