MCP3462RT-E/ST Frequently Asked Questions (FAQs)

  • Microchip recommends following a star-grounding scheme, using a solid ground plane, and keeping analog and digital signals separate to minimize noise. Additionally, use short and direct traces for the analog inputs and outputs, and avoid routing digital signals near the analog signals.
  • Calibration involves adjusting the gain and offset of the ADC to match the specific application requirements. Microchip provides a calibration procedure in the datasheet, which involves applying a known input voltage and adjusting the gain and offset registers to achieve the desired output code.
  • The maximum sampling rate of the MCP3462RT-E/ST is 500 ksps. As the sampling rate increases, the power consumption also increases. To minimize power consumption, it is recommended to use the lowest sampling rate required for the application.
  • The MCP3462RT-E/ST has built-in overvoltage protection up to 5V. For undervoltage conditions, it is recommended to use a voltage clamp or a voltage limiter circuit to prevent damage to the ADC. Additionally, consider using a voltage regulator to ensure a stable voltage supply to the ADC.
  • The recommended power-up sequence is to apply the analog voltage (VDDA) first, followed by the digital voltage (VDD). This ensures that the analog circuitry is powered up before the digital circuitry, which helps to prevent latch-up and ensures proper operation.
