MCP6N11 Instrumentation Amplifier Wheatstone Bridge Reference Design

This board demonstrates the performance of Microchips MCP6N11 instrumentation amplifier (INA) and a traditional three op amp INA using Microchips 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 bridges output, to provide realistic performance comparisons. Data is gathered and displayed on a PC, for ease of use. The USB PICmicro® microcontroller and included Graphical User Interface (GUI) provides the means to configure the board and collect sample data.

Features and Benefits:

RTD temperature sensorINA signal conditioningPICmicro signal conditioning and communicationsPC software (GUI): Thermal Management Utility

Software:

Microchip provides a free software called 'Thermal Management Utility'. You can find a link for it below. Thermal Management Utility handles communications through the USB connected to your board and will display data on a strip chart. It can store single points of calibration ecoefficiency on the PIC MCU and tells the PIC MCU how to configure the average filter. http://ww1.microchip.com/downloads/en/DeviceDoc/ThermalManagementUtility-v1.5.8.zip
