MCP621/2/5
20 MHz, 2.5 mA Op Amps with mCal
Features
Description
• Gain Bandwidth Product: 20 MHz (typical)
• Short Circuit Current: 70 mA (typical)
• Noise: 13 nV/√Hz (typical, at 1 MHz)
• Calibrated Input Offset: ±200 µV (maximum)
• Rail-to-Rail Output
The Microchip Technology, Inc. MCP621/2/5 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.
• Slew Rate: 10 V/µs (typical)
• Supply Current: 2.5 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
(MCP621), dual (MCP622) and dual with CAL/CS pins
(MCP625). All devices are fully specified from -40°C to
+125°C.
