Status: In Production
The 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 over temperature. The supply voltage range of 1.8V to 5.5V is low enough to support many portable applications. All devices are fully specified from -40 to +125C.
This board demonstrates the performance of Microchip’s MCP6N11 instrumentation amplifier (INA) and a traditional three op amp INA using Microchip’s MCP6V26 and MCP6V27 auto-zeroed op amps. The input signal comes from an RTD temperature sensor in a Wheatstone bridge. Real world interference is added to the bridge’s output, to provide realistic performance comparisons. Data is...
