MCP631/2/3/4/5/9

24 MHz, 2.5 mA Rail-to-Rail Output (RRO) Op Amps

Features:

Description:

• Gain-Bandwidth Product: 24 MHz

• Slew Rate: 10 V/µs

The Microchip Technology Inc. MCP631/2/3/4/5/9

family of operational amplifiers features high gain

bandwidth product (24 MHz, typical) and high output

short-circuit current (70 mA, typical). Some also

provide a Chip Select (CS) pin that supports a

low-power mode of operation. 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.

• Noise: 10 nV/Hz at 1 MHz)

• Low Input Bias Current: 4 pA (typical)

• Ease of Use:

- Unity-Gain Stable

- Rail-to-Rail Output

- Input Range including Negative Rail

- No Phase Reversal

This family is offered in single (MCP631), single with

CS pin (MCP633), dual (MCP632), dual with two CS

pins (MCP635), quad (MCP634) and quad with two

Chip Select pins (MCP639). All devices are fully

specified from -40°C to +125°C.

• Supply Voltage Range: +2.5V to +5.5V

• High Output Current: ±70 mA

• Supply Current: 2.5 mA/ch (typical)

• Low-Power Mode: 1 µA/ch

• Small Packages: SOT23-5, DFN

• Extended Temperature Range: -40°C to +125°C
