DAC6574IDGS datasheet by Texas Instruments

DAC6574IDGS Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC6574?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC). This ensures that the analog circuitry is powered up before the digital circuitry.
• How do I ensure accurate voltage output from the DAC6574?
  To ensure accurate voltage output, it is essential to use a stable reference voltage, minimize noise on the analog input pins, and use a low-noise power supply. Additionally, ensure that the output voltage is within the specified range of 0 to VREF.
• What is the maximum output current of the DAC6574?
  The maximum output current of the DAC6574 is 5 mA. Exceeding this current may cause damage to the device or affect its accuracy.
• Can I use the DAC6574 with a 3.3V or 1.8V digital supply?
  Yes, the DAC6574 can operate with a 3.3V or 1.8V digital supply. However, the device's performance may be affected, and the output voltage range may be limited. Consult the datasheet for specific details.
• How do I handle the DAC6574's output during power-down or reset?
  During power-down or reset, the DAC6574's output may go to an undefined state. To avoid this, use an external pull-down resistor or a buffer amplifier to ensure a defined output state.
