This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

MICROCHIP Zero-Drift Linear Op Amps

Microchip Technology’s MCP6V76, 76U, 77, and 79 are zero-drift linear op amps ideal for portable instrumentation, medical devices, and other applications requiring precise and stable measurements. 

The op amps have input offset voltage correction, resulting in very low input offset and drift, combined with virtually no 1/f noise, high PSRR, and high CMRR, while the enhanced EMI protection provides a high EMI rejection ratio to minimize external interference. The op amps are also easy to use as they are unity gain stable, have a 2MHz gain bandwidth product and have rail-to-rail inputs and outputs. 

The family includes single, dual, and quad channel options in compact packages, and operates from a 2V to 5.5V supply with a 170µA quiescent current per channel. 

  • Input offset correction: 
    • ±25µV (maximum) input offset voltage 
    • ±150nV/°C (maximum) input offset voltage drift
