AD5270BRMZ-20-RL7 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD before applying VLOGIC. This ensures that the internal voltage regulator is powered up before the digital logic.
  • To ensure that the AD5270 is in a known state after power-up, it is recommended to perform a software reset by writing 0x0000 to the Command Register (Address 0x00) after power-up.
  • The maximum capacitance that can be driven by the AD5270's digital output pins is 100 pF. Exceeding this limit may affect the device's performance and reliability.
  • To implement an NVM recall function, write the desired wiper position to the Wiper Register (Address 0x01) and then write 0x01 to the Command Register (Address 0x00) to store the wiper position in NVM. During power-up, the AD5270 will automatically recall the stored wiper position from NVM.
  • To minimize noise and ensure reliable operation, it is recommended to keep the digital and analog signal paths separate, use a solid ground plane, and avoid running digital signals near the analog inputs. Additionally, use a 10 nF to 100 nF decoupling capacitor between VDD and GND, and a 1 μF to 10 μF decoupling capacitor between VLOGIC and GND.
