The Microchip MCP6N11 single instrumentation amplifier is optimized for single-supply operation with rail-to-rail input and output performance. Two external resistors set the gain, minimizing gain error and drift overtemperature. The supply voltage range of 1.8 V to 5.5 V is low enough to support many portable applications. The MCP6N16 is a zero-drift operational amplifier designed for single-supply operation with rail-to-rail input (no common mode crossover distortion) and output performance. The supply voltage range is low enough to support many portable applications. Each device has EMI filters at the input pins, providing superior EMI rejection. This family has three minimum gain options 1, 10, and 100 V/V to allow the user to optimize the input offset voltage and input noise for different applications. All devices are fully specified from -40°C to +125°C.
