Product Overview

The ARD00354 is an MCP6N11 and MCP6V2x Wheatstone Bridge Reference Design board that demonstrates the performance of MCP6N11 instrumentation amplifier (INA) and a traditional three op amp INA using 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 gathered and displayed on a PC, for ease of use. The USB PIC microcontroller and included Graphical User Interface (GUI) show how to implement these functions. This board uses an RTD temperature sensor, in a Wheatstone bridge, to measure the board's temperature. The bridge's output is a small Differential mode (DM) signal with a large Common mode (CM) interference signal superimposed. The CM signal is a PWM waveform generated by the microcontroller, which simulates real world interference.
