MCP4251-103E/ST Frequently Asked Questions (FAQ)

  • The recommended power-on sequence is to apply VDD before applying VSS. This ensures that the internal voltage regulator is properly initialized.

  • The MCP4251-103E/ST has a power-on reset (POR) circuit that initializes the digital potentiometer to its mid-scale position (128 taps) after power-up. However, it's recommended to send a 'reset' command (0x00) to the device after power-up to ensure that the digital potentiometer is properly initialized.

  • The maximum voltage that can be applied to the RH and RL pins is VDD + 0.3V. Exceeding this voltage may damage the device.

  • To prevent accidental changes to the digital potentiometer during power-up or power-down, it's recommended to tie the CS pin low during these transitions. This ensures that the device is in a 'sleep' mode and ignores any incoming SPI commands.

  • The maximum frequency of the SPI clock that can be used with the MCP4251-103E/ST is 10 MHz. Exceeding this frequency may result in unreliable operation or data corruption.
