Working Principles

The MCP6V14-E/ST is a precision instrumentation amplifier that amplifies small signals with high accuracy. It consists of a differential input stage, a gain stage, and an output buffer. The differential input stage amplifies the voltage difference between Vin+ and Vin-, while the gain stage provides additional amplification based on the selected gain setting. The output buffer then drives the amplified signal to the Vout+ and Vout- pins.
