MCP3221A2T-E/OT Frequently Asked Questions (FAQ)

  • Microchip recommends a 4-layer PCB with a solid ground plane, and placing the ADC as close as possible to the analog signal sources. Additionally, use a separate analog ground plane and keep digital signals away from the ADC.

  • The MCP3221A2T-E/OT has an internal calibration circuit that can be used to calibrate the ADC. The calibration process involves writing a specific code to the calibration register, and then reading the calibration result from the ADC output register.

  • The maximum sampling rate of the MCP3221A2T-E/OT is 22,000 samples per second. The power consumption increases with the sampling rate, so it's essential to balance the sampling rate with power consumption requirements.

  • The MCP3221A2T-E/OT has a sleep mode that can be enabled by writing a specific code to the control register. The wake-up time is approximately 2 μs, and it's essential to ensure that the device is in a stable state before taking a conversion.

  • The recommended input signal range is 0 to VREF (2.5V or 5V), and the input impedance should be less than 1 kΩ to ensure accurate conversions.
