DAC716UB datasheet by Texas Instruments

DAC716UB Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC716UB?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the internal voltage regulators are powered up correctly.
• How do I ensure accurate voltage output from the DAC716UB?
  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 DAC716UB?
  The maximum output current of the DAC716UB is 5 mA. Exceeding this current may cause damage to the device or affect its accuracy.
• Can I use the DAC716UB in a ratiometric configuration?
  Yes, the DAC716UB can be used in a ratiometric configuration, where the output voltage is proportional to the supply voltage. This can be useful in applications where the output voltage needs to track the supply voltage.
• How do I handle the digital interface of the DAC716UB?
  The DAC716UB has a 16-bit parallel digital interface. Ensure that the digital signals are properly terminated and that the clock frequency is within the recommended range of 5-40 MHz.
