DAC5672IPFB datasheet by Texas Instruments

DAC5672IPFB Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC5672IPFB?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC). This ensures that the analog and digital sections of the device are powered up correctly.
• How do I ensure accurate voltage output from the DAC5672IPFB?
  To ensure accurate voltage output, it is essential to use a stable reference voltage, ensure proper PCB layout and decoupling, and follow the recommended output filtering and buffering configurations.
• What is the maximum output current of the DAC5672IPFB?
  The maximum output current of the DAC5672IPFB is 10 mA. Exceeding this current may cause damage to the device or affect its performance.
• How do I handle the DAC5672IPFB's digital interface?
  The DAC5672IPFB's digital interface is a 3-wire serial interface. Ensure that the clock frequency is within the recommended range (10 kHz to 50 MHz), and use a pull-up resistor on the SCL line to prevent bus contention.
• What is the purpose of the DAC5672IPFB's internal reference voltage?
  The internal reference voltage (VREF) is used to set the full-scale output voltage of the DAC. It can be bypassed using an external reference voltage if required.
