DAC084S085CIMMX/NOPB datasheet by Texas Instruments

DAC084S085CIMMX/NOPB Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC084S085?
  The recommended power-up sequence is to apply VCC first, followed by the digital supply (VDD), and then the analog supply (VREF). This ensures proper device operation and prevents latch-up.
• How do I ensure accurate output voltage levels from the DAC084S085?
  To ensure accurate output voltage levels, it is essential to use a low-impedance reference voltage source (VREF) and to decouple the analog supply (VCC) with a 10uF capacitor to reduce noise and ripple.
• What is the maximum clock frequency supported by the DAC084S085?
  The DAC084S085 supports clock frequencies up to 40 MHz, but the maximum frequency may vary depending on the specific application and system constraints.
• Can I use the DAC084S085 in a ratiometric configuration?
  Yes, the DAC084S085 can be used in a ratiometric configuration, where the reference voltage (VREF) is derived from the analog supply (VCC). This configuration can simplify the design and reduce the number of external components.
• How do I handle the output voltage settling time of the DAC084S085?
  The output voltage settling time of the DAC084S085 is typically around 10-15 ns. To ensure accurate output voltage levels, it is recommended to add a settling time of at least 20-30 ns before taking a measurement or using the output voltage in the application.
