DAC8718SPAGR datasheet by Texas Instruments

DAC8718SPAGR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC8718?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC). This ensures proper device operation and prevents latch-up.
• How do I configure the DAC8718 for unipolar or bipolar output?
  The DAC8718 can be configured for unipolar or bipolar output by setting the UNIPOLAR/BIPOLAR pin (Pin 15) high or low, respectively. For unipolar output, tie the pin to VCC, and for bipolar output, tie it to GND.
• What is the maximum output current of the DAC8718?
  The maximum output current of the DAC8718 is 20 mA. Exceeding this limit may cause device damage or affect its performance.
• How do I implement a voltage reference for the DAC8718?
  The DAC8718 requires an external voltage reference (VREF) to operate. You can use an external voltage reference IC, such as the REF3020, or a resistive divider network to generate the reference voltage.
• What is the settling time of the DAC8718?
  The settling time of the DAC8718 is typically 10 μs, but it can vary depending on the output voltage, load, and other factors. Ensure that your system design accounts for this settling time to ensure accurate conversions.
