DAC8881SRGER datasheet by Texas Instruments

DAC8881SRGER Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC8881?
  The recommended power-up sequence is to apply VDD first, followed by VREF, and then the digital interface signals. This ensures proper device operation and prevents potential latch-up conditions.
• How do I handle the output voltage range of the DAC8881?
  The DAC8881 has a rail-to-rail output stage, but the output voltage range is limited by the VREF voltage. Ensure that the output voltage range is within the specified range of VREF to avoid output clipping or distortion.
• What is the effect of clock jitter on the DAC8881's performance?
  Clock jitter can affect the DAC8881's performance by introducing noise and distortion in the output signal. It is recommended to use a low-jitter clock source and to follow proper PCB layout and design practices to minimize clock jitter.
• How do I implement a bipolar output voltage range using the DAC8881?
  To implement a bipolar output voltage range, use an external op-amp to invert and scale the output voltage. This requires careful selection of the op-amp and resistors to ensure proper operation and stability.
• What is the maximum update rate of the DAC8881?
  The maximum update rate of the DAC8881 is 1 MSPS, but this can be limited by the digital interface and the system's clock frequency. Ensure that the update rate is within the specified range to avoid data corruption or errors.
