DAC900E datasheet by Texas Instruments

DAC900E Frequently Asked Questions (FAQs)

• What is the maximum output current of the DAC900E?
  The maximum output current of the DAC900E is 5mA per channel.
• How do I ensure monotonicity of the DAC900E?
  To ensure monotonicity, use a clock frequency of at least 10 times the update rate, and ensure that the input data is properly synchronized with the clock signal.
• What is the effect of temperature on the DAC900E's performance?
  The DAC900E's performance is affected by temperature, with a typical drift of 10ppm/°C. Ensure proper thermal management and consider using a temperature compensation circuit if necessary.
• Can I use the DAC900E in a single-supply system?
  Yes, the DAC900E can be used in a single-supply system, but ensure that the output voltage is within the specified range (0 to VCC) and that the reference voltage is properly set.
• How do I handle the DAC900E's power-on reset (POR) circuitry?
  The POR circuitry ensures that the DAC900E resets to a known state on power-up. Ensure that the power supply is stable and that the POR pin is properly connected to a capacitor to ground.
