DAC8555IPW datasheet by Texas Instruments

DAC8555IPW Frequently Asked Questions (FAQs)

• What is the maximum output current of the DAC8555IPW?
  The maximum output current of the DAC8555IPW 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 DAC8555IPW?
  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 internal voltage regulators.
• How do I handle the DAC8555IPW's output glitch during power-on?
  To minimize output glitches during power-on, use an external pull-down resistor on the output pin, and consider using a power-on reset circuit to ensure a clean startup.
• What is the maximum capacitance allowed on the output pins?
  The maximum capacitance allowed on the output pins is 100nF. Exceeding this value may affect the stability of the output stage.
