MCP4661-502E/ST Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD before applying the clock signal. This ensures that the internal circuitry is properly initialized.
  • To retain the wiper position during power-down, the CS pin should be held high and the SCK pin should be held low. This ensures that the wiper position is latched and retained during power-down.
  • The maximum frequency of the clock signal that can be used with the MCP4661-502E/ST is 1 MHz. Exceeding this frequency may result in incorrect operation or damage to the device.
  • Yes, the MCP4661-502E/ST can be used in a ratiometric application. The device's internal resistors are ratio-metric, meaning that the resistance ratio between the wiper and the A/B terminals is maintained, even if the supply voltage changes.
  • When the wiper is at the extreme ends of the resistor array, the resistance between the wiper and the A/B terminals may not be exactly 0 ohms or the total resistance of the array. This is due to the internal architecture of the device. To handle this situation, it is recommended to add external resistors to the circuit to ensure the desired resistance ratio.
