MCP3903-E/SS Frequently Asked Questions (FAQs)

  • Microchip provides a recommended layout and routing guide in the MCP3903-E/SS datasheet, which includes guidelines for PCB layout, component placement, and routing to minimize noise and ensure optimal performance.
  • The MCP3903-E/SS has an internal calibration mechanism, but it may require external calibration for high-accuracy applications. Microchip provides a calibration procedure in the datasheet, which involves applying a known input voltage and adjusting the internal calibration registers.
  • The maximum input voltage range for the MCP3903-E/SS is ±650 mV, but it can be extended to ±1000 mV with external attenuation. However, it's essential to ensure that the input voltage does not exceed the absolute maximum rating of ±1.2 V to prevent damage to the device.
  • The MCP3903-E/SS has internal overvoltage protection, but it's recommended to add external protection circuitry, such as a voltage clamp or a transient voltage suppressor, to protect the device from high-voltage transients and surges.
  • The recommended power-up sequence for the MCP3903-E/SS is to apply the analog power supply (AVDD) before the digital power supply (DVDD). This ensures that the analog circuitry is powered up before the digital circuitry to prevent any potential latch-up conditions.
