MCP3551-E/MS Frequently Asked Questions (FAQs)

  • Microchip recommends a 4-layer PCB with a solid ground plane, and to keep analog and digital signals separate. Use short, direct traces for the analog inputs and outputs, and avoid crossing digital signals over the analog signals.
  • Calibration involves adjusting the internal offset and gain of the ADC. Microchip provides a calibration procedure in the datasheet, which involves applying a known input voltage and adjusting the offset and gain registers accordingly.
  • The maximum sampling rate of the MCP3551-E/MS is 200 ksps. As the sampling rate increases, the power consumption also increases. However, the power consumption can be reduced by using the device's power-down modes or by reducing the clock frequency.
  • The MCP3551-E/MS has internal overvoltage protection up to 5V. However, it's recommended to use external protection circuitry, such as voltage dividers or clamp circuits, to prevent damage from higher voltage transients.
  • Yes, the MCP3551-E/MS can be used in a multiplexed configuration. To do so, connect multiple analog inputs to the device and use the MUX registers to select the desired input channel. The device will then convert the selected input and store the result in the conversion register.
