DAC7634EB/1K datasheet by Texas Instruments

DAC7634EB/1K Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC7634EB/1K?
  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 DAC7634EB/1K?
  To ensure accurate voltage output, it is essential to use a low-noise, low-impedance voltage reference, and to decouple the output with a capacitor to filter out noise and ripple.
• What is the maximum output current capability of the DAC7634EB/1K?
  The maximum output current capability of the DAC7634EB/1K is 5mA. Exceeding this limit may cause the output voltage to droop or the device to overheat.
• How do I handle the digital inputs to the DAC7634EB/1K during power-down or reset?
  During power-down or reset, it is recommended to hold the digital inputs in a static state (either high or low) to prevent unwanted output voltage transitions.
• What is the effect of temperature on the DAC7634EB/1K's performance?
  The DAC7634EB/1K's performance may be affected by temperature changes, which can cause output voltage drift and gain errors. It is essential to consider temperature compensation or calibration in the system design.
