DAC5672AIPFB datasheet by Texas Instruments

DAC5672AIPFB Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC5672AIPFB?
  The recommended power-up sequence is to apply the analog supply voltage (AVCC) first, followed by the digital supply voltage (DVCC), and then the clock signal. This ensures proper initialization of the device.
• How do I ensure accurate voltage output from the DAC5672AIPFB?
  To ensure accurate voltage output, it is essential to use a low-noise, low-impedance voltage reference, and to decouple the analog supply voltage (AVCC) with a 10uF capacitor. Additionally, the output voltage should be filtered with a low-pass filter to reduce noise and ripple.
• What is the maximum clock frequency that can be used with the DAC5672AIPFB?
  The maximum clock frequency that can be used with the DAC5672AIPFB is 40 MHz. However, the actual clock frequency used may be limited by the specific application and the required data transfer rate.
• How do I handle the SYNC pin on the DAC5672AIPFB?
  The SYNC pin is used to synchronize the DAC's output with an external clock signal. It should be tied to the digital ground (DGND) if not used. If used, it should be connected to a clock signal that is synchronized with the data transfer clock.
• What is the purpose of the CLR pin on the DAC5672AIPFB?
  The CLR pin is an active-low clear input that resets the DAC's output to zero when asserted low. It can be used to reset the DAC's output to a known state during power-up or when the device is not in use.
