DAC8574IPW datasheet by Texas Instruments

DAC8574IPW Frequently Asked Questions (FAQs)

• What is the maximum output current of the DAC8574IPW?
  The maximum output current of the DAC8574IPW is 5mA per channel.
• How do I ensure monotonicity of the DAC output?
  To ensure monotonicity, use a clock frequency of at least 10 times the update rate, and ensure that the input data is properly formatted and synchronized with the clock signal.
• What is the recommended power-on sequence for the DAC8574IPW?
  The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC). This ensures proper initialization of the device.
• How do I handle the DAC8574IPW's power-down mode?
  To enter power-down mode, assert the PD pin low. In this mode, the DAC output is high-impedance, and the device consumes minimal power. To exit power-down mode, de-assert the PD pin.
• What is the purpose of the DAC8574IPW's offset binary coding?
  The offset binary coding allows for a more efficient use of the DAC's output range, enabling the device to produce a true zero-scale output voltage.
