DAC811AH datasheet by Texas Instruments

DAC811AH Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC811AH?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures proper device operation and prevents latch-up.
• How do I ensure accurate voltage output from the DAC811AH?
  To ensure accurate voltage output, it's essential to use a stable reference voltage, minimize noise on the analog input, 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 DAC811AH?
  The maximum output current of the DAC811AH is 10 mA. Exceeding this current may cause damage to the device or affect its accuracy.
• Can I use the DAC811AH in a ratiometric configuration?
  Yes, the DAC811AH can be used in a ratiometric configuration, where the output voltage is proportional to the reference voltage. This configuration is useful in applications where the output voltage needs to track changes in the reference voltage.
• How do I handle the DAC811AH's digital inputs during power-down or reset?
  During power-down or reset, it's recommended to keep the digital inputs in a high-impedance state or pull them up to a valid logic level to prevent unwanted device operation or latch-up.
