DAC7311IDCKR datasheet by Texas Instruments

DAC7311IDCKR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC7311?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly.
• How do I ensure accurate voltage output from the DAC?
  To ensure accurate voltage output, it is essential to use a high-quality voltage reference, such as the Texas Instruments REF5025. Additionally, ensure that the output voltage is buffered with an op-amp, such as the OPA333, to prevent loading effects.
• What is the maximum output current of the DAC7311?
  The maximum output current of the DAC7311 is 5mA. Exceeding this current may cause damage to the device or affect its accuracy.
• How do I handle the digital interface of the DAC7311?
  The DAC7311 has a 16-bit parallel digital interface. Ensure that the digital inputs are properly terminated and that the clock frequency is within the recommended range of 10MHz to 40MHz.
• What is the settling time of the DAC7311?
  The settling time of the DAC7311 is typically 10μs, but this can vary depending on the output voltage, load capacitance, and other factors. Ensure that the output voltage has settled before taking a measurement.
