Microchip Instrumentation Amplifier with mCAL Technology
The MCP6N11 and MCP6V2x Wheatstone Bridge Reference Design demo on the right shows 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 a Resistive Temperature Detector (RTD) sensor in a Wheatstone bridge. Real-world interference is added to the bridge's 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) provide the means to configure the board and collect sample data.
If you need to work with Microchip Support staff directly, you can submit a technical support case. Keep in mind that many questions can be answered through our self-help resources, so this may not be your speediest option.
