DAC5674IPHP datasheet by Texas Instruments

DAC5674IPHP Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC5674IPHP?
  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 DAC5674IPHP?
  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 filtered using a low-pass filter to reduce noise and ripple.
• What is the maximum output current of the DAC5674IPHP?
  The maximum output current of the DAC5674IPHP is 10 mA per channel. Exceeding this current limit may cause damage to the device or affect its accuracy.
• How do I synchronize multiple DAC5674IPHP devices?
  To synchronize multiple DAC5674IPHP devices, connect the SYNC pin of each device together and drive it with a common clock signal. This ensures that all devices update their outputs simultaneously.
• What is the purpose of the CLR pin on the DAC5674IPHP?
  The CLR pin is an active-low input that clears the output voltage to zero when asserted low. This pin can be used to reset the output voltage to zero during power-up or when a reset is required.
