DAC7574IDGSR datasheet by Texas Instruments

DAC7574IDGSR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC7574?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly.
• How do I ensure accurate voltage output from the DAC?
  To ensure accurate voltage output, make sure to use a stable reference voltage, keep the analog and digital grounds separate, and use a low-noise power supply. Additionally, consider using a voltage reference buffer amplifier to reduce noise and improve accuracy.
• What is the maximum output current of the DAC7574?
  The maximum output current of the DAC7574 is 5mA. Exceeding this current may cause damage to the device or affect its accuracy.
• Can I use the DAC7574 with a 3.3V power supply?
  Yes, the DAC7574 can operate with a 3.3V power supply. However, the output voltage range will be limited to 0-3.3V. Make sure to adjust the reference voltage and output voltage accordingly.
• How do I handle the DAC7574's digital inputs during power-up and power-down?
  During power-up and power-down, it's recommended to keep the digital inputs in a high-impedance state or tie them to a fixed logic level to prevent unwanted output voltage transitions.
