DAC902U datasheet by Texas Instruments

DAC902U Frequently Asked Questions (FAQs)

• What is the recommended output load impedance for the DAC902U?
  The recommended output load impedance for the DAC902U is 2 kΩ or higher to ensure accurate voltage output and to prevent output voltage droop.
• How do I ensure monotonicity when using the DAC902U?
  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. Additionally, use a stable and low-noise power supply to minimize output glitches.
• What is the maximum update rate of the DAC902U?
  The maximum update rate of the DAC902U is 30 MSPS (mega-samples per second), but this can be limited by the clock frequency, input data rate, and other system-level factors.
• How do I handle the DAC902U's power-on reset (POR) and brown-out reset (BOR)?
  The DAC902U has a built-in POR and BOR circuitry that resets the device during power-up or brown-out conditions. To handle this, ensure that the input data is held in a valid state during power-up, and use external circuitry to debounce the reset signal if necessary.
• What is the effect of temperature on the DAC902U's performance?
  The DAC902U's performance can be affected by temperature, with changes in gain, offset, and linearity. To minimize temperature effects, use a stable and temperature-controlled environment, and consider using external temperature compensation circuitry if necessary.
