DAC902E 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 circuitry is powered up before the digital circuitry.
  • To ensure accurate voltage output, it is essential to use a low-noise, low-impedance voltage reference (VREF) and to decouple the VREF pin with a capacitor. Additionally, the output voltage should be buffered with an op-amp to prevent loading effects.
  • The maximum output current of the DAC902E is 5 mA. Exceeding this current may cause damage to the device or affect its accuracy.
  • During asynchronous updates, the SYNC pin should be held low to prevent the DAC from updating the output voltage. When the SYNC pin is high, the DAC updates the output voltage based on the input data.
  • The CLR pin is used to clear the DAC output to a zero-scale voltage. To use it, pull the CLR pin low to clear the output, and then release it to allow the DAC to update the output voltage based on the input data.
