Our Instrumentation Amplifiers (INAs) include internal matched feedback and are ideal for data acquisition applications. Their ability to accurately extract a small signal in the presence of a large common mode makes these INAs ideal for sensor amplification. Electromagnetic Interference (EMI) filtering on select devices maintains excellent performance in the most demanding environments.

Highlights

  • Using high-precision architectures enables superior DC performance, regardless of operating conditions
  • Low noise and additional EMI filtering on the inputs provide additional protection in electrically noisy environments
  • Small packages, such as leadless DFNs, are ideal for space-constrained designs
  • A wide operating temperature range of –40°C to +125°C provides a robust solution even at extreme temperatures

Microchip Instrumentation Amplifier with mCAL Technology

The MCP6N11 and MCP6V2x Wheatstone Bridge Reference Design 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 gathered and displayed on a PC, for ease of use. The USB PIC® microcontroller and included Graphical User Interface (GUI) provides the means to configure the board and collect sample data.
