DAC7611UB/2K5 datasheet by Texas Instruments

DAC7611UB/2K5 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC7611UB/2K5?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures proper device operation and prevents latch-up.
• How do I ensure accurate voltage output from the DAC7611UB/2K5?
  To ensure accurate voltage output, it is essential to use a low-noise, low-impedance voltage reference, and to decouple the VREF pin with a capacitor to reduce noise and oscillations.
• What is the maximum output current of the DAC7611UB/2K5?
  The maximum output current of the DAC7611UB/2K5 is 5 mA. Exceeding this current may cause damage to the device or affect its accuracy.
• How do I handle the SYNC pin during asynchronous updates?
  During asynchronous updates, the SYNC pin should be held low to prevent the DAC from updating the output voltage. This ensures that the output voltage remains stable during the update process.
• What is the purpose of the CLR pin, and how do I use it?
  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 to the new output voltage.
