DAC7621E/1K Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC). This ensures that the analog and digital sections of the device are powered up correctly.
  • To ensure accurate voltage output, make sure to use a stable and low-noise voltage reference, and decouple the VREF pin with a capacitor to reduce noise. Additionally, use a low-impedance output buffer amplifier if the output is driving a load.
  • The maximum output current of the DAC7621E/1K is 5 mA. Exceeding this current may cause the output voltage to droop or the device to overheat.
  • During asynchronous updates, the SYNC pin should be held low to prevent the DAC from updating the output voltage. When the SYNC pin is low, the DAC ignores the input data and holds the current output voltage.
  • The CLR pin is an active-low clear input that resets the DAC output to zero scale (minimum output voltage) when asserted low. Use the CLR pin to reset the DAC output to a known state during power-up or when the system requires a reset.
