DAC8581IPW datasheet by Texas Instruments

DAC8581IPW Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC8581IPW?
  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 DAC8581IPW?
  To ensure accurate voltage output, it is essential to use a high-quality voltage reference, such as the Texas Instruments REF5025. Additionally, the DAC output should be filtered using a low-pass filter to remove any high-frequency noise.
• What is the maximum output current of the DAC8581IPW?
  The maximum output current of the DAC8581IPW is 5 mA. Exceeding this current limit may cause damage to the device or affect its accuracy.
• Can I use the DAC8581IPW in a ratiometric configuration?
  Yes, the DAC8581IPW can be used in a ratiometric configuration, where the output voltage is proportional to the supply voltage. This can be useful in applications where the output voltage needs to track the supply voltage.
• How do I handle the DAC8581IPW's digital inputs during power-up and power-down?
  During power-up and power-down, the digital inputs should be held in a valid logic state to prevent unwanted output voltage transitions. It is recommended to use a pull-up or pull-down resistor to ensure a valid logic state.
