DAC81416RHAR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a star-ground topology, with the analog and digital grounds separated and connected at a single point. Additionally, keep the analog and digital signal traces separate, and use a solid ground plane to reduce noise and electromagnetic interference (EMI).
  • The internal reference voltage can be configured using the REFSEL pin. Connect REFSEL to VREFIN (pin 14) for an internal 2.5V reference, or to GND for an internal 1.25V reference. Ensure the reference voltage is stable and within the recommended range to maintain accurate DAC performance.
  • The maximum output current of the DAC81416RHAR is 10mA. The output voltage range is affected by the load current, with a maximum output voltage of VDD - 0.5V when driving a 10kΩ load. Ensure the output current is within the recommended range to maintain accurate output voltage levels.
  • The DAC81416RHAR has a built-in POR and BOR feature that resets the device during power-up or brown-out conditions. Ensure that the power supply is stable and within the recommended range to prevent unwanted resets. You can also use external circuitry to filter or debounce the power supply to reduce the likelihood of unwanted resets.
  • The recommended clock frequency for the DAC81416RHAR's serial interface is between 10kHz and 50MHz. Ensure the clock signal is stable and has a duty cycle of 40% to 60%. The data should be valid on the rising edge of the clock, and the clock should be high for at least 10ns to ensure proper data transfer.
