MCP651/2/5 50 MHz, 6 mA Op Amps with mCal Features
Description
• • • • • • • • •
The Microchip Technology, Inc. MCP651/2/5 family of operational amplifiers features low offset. At power up, these op amps are self-calibrated using mCal. Some package options also provide a calibration/chip select pin (CAL/CS) that supports a low power mode of operation, with offset calibration at the time normal operation is re-started. These amplifiers are optimized for high speed, low noise and distortion, single-supply operation with rail-to-rail output and an input that includes the negative rail.
Gain Bandwidth Product: 50 MHz (typical) Short Circuit Current: 100 mA (typical) Noise: 7.5 nV/√Hz (typical, at 1 MHz) Calibrated Input Offset: ±200 µV (maximum) Rail-to-Rail Output Slew Rate: 30 V/µs (typical) Supply Current: 6.0 mA (typical) Power Supply: 2.5V to 5.5V Extended Temperature Range: -40°C to +125°C
This family is offered in single with CAL/CS pin (MCP651), dual (MCP652) and dual with CAL/CS pins (MCP655). All devices are fully specified from -40°C to +125°C.
