Microchip Technology MCP6V7x Zero-Drift Linear Op Amps

Microchip Technology MCP6V7x Zero-Drift Linear Operational Amplifiers (Op Amps) provide input offset voltage correction for very low offset and offset drift. These are low-power devices with a typical gain bandwidth of 2MHz. The MCP6V7x Op Amps are unity-gain stable, have virtually no 1/f noise, and have good Power Supply Rejection Ratio (PSRR) and Common Mode Rejection Ratio (CMRR). These devices operate with a single supply voltage as low as 2V, drawing 170µA/amplifier (typical) of quiescent current.

The MCP6V7x Op Amps from Microchip Technology have enhanced EMI protection to minimize any electromagnetic interference from external sources. This feature makes these devices well suited for EMI sensitive applications such as power lines, radio stations, and mobile communications.

The MCP6V7x Op Amps are designed using an advanced CMOS process and are offered in single (MCP6V76 and MCP6V76U), dual (MCP6V77), and quad (MCP6V79) packages.
