DAC6573IPWR datasheet by Texas Instruments

DAC6573IPWR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC6573IPWR?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC). This ensures proper device operation and prevents latch-up.
• How do I ensure accurate voltage output from the DAC6573IPWR?
  To ensure accurate voltage output, it is essential to use a low-noise, low-impedance voltage reference (VREF) and to decouple the VREF pin with a capacitor. Additionally, ensure that the output voltage is within the specified range (0 to VREF) and that the load impedance is within the recommended range.
• What is the maximum output current of the DAC6573IPWR?
  The maximum output current of the DAC6573IPWR is 5 mA. Exceeding this current may cause the output voltage to droop or the device to overheat.
• How do I interface the DAC6573IPWR with a microcontroller?
  The DAC6573IPWR can be interfaced with a microcontroller using a serial interface (SPI or I2C). Ensure that the microcontroller's clock frequency is within the recommended range (fCLK = 10 MHz to 40 MHz for SPI and 100 kHz to 400 kHz for I2C) and that the interface lines are properly terminated.
• What is the purpose of the CLR pin on the DAC6573IPWR?
  The CLR (Clear) pin is an active-low input that resets the DAC's output to zero-scale (0 V) when pulled low. This pin can be used to reset the DAC's output during power-up or when a reset is required.
