Description

The Microchip Technology Inc. MCP6V31/1U family of

operational amplifiers provides input offset voltage

correction for very low offset and offset drift. These are

low power devices, with a gain bandwidth product of

300 kHz (typical). They are unity gain stable, have no

1/f noise, and have good Power Supply Rejection Ratio

(PSRR) and Common Mode Rejection Ratio (CMRR).

These products operate with a single supply voltage as

low as 1.8V, while drawing 23 µA/amplifier (typical) of

quiescent current.

The Microchip Technology Inc. MCP6V31/1U op amps

are offered in single (MCP6V31 and MCP6V31U)

packages. They were designed using an advanced

CMOS process.
