DAC122S085CIMMX/NOPB datasheet by Texas Instruments

DAC122S085CIMMX/NOPB Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC122S085?
  The recommended power-up sequence is to apply VDD first, followed by VREF, and then the digital inputs. This ensures proper device operation and prevents potential latch-up conditions.
• How do I handle the output voltage settling time of the DAC122S085?
  The output voltage settling time of the DAC122S085 is typically around 10-15 μs. To ensure accurate readings, it's recommended to wait for at least 20-30 μs after updating the DAC register before taking a measurement.
• What is the maximum output current of the DAC122S085?
  The maximum output current of the DAC122S085 is 5 mA. Exceeding this current may cause the output voltage to droop or the device to overheat.
• Can I use the DAC122S085 with a capacitive load?
  Yes, but with caution. The DAC122S085 can drive capacitive loads up to 100 pF. However, larger capacitive loads may cause oscillations or instability. It's recommended to add a series resistor to dampen the output and ensure stability.
• How do I minimize noise and interference when using the DAC122S085?
  To minimize noise and interference, use a low-noise power supply, keep the analog and digital grounds separate, and use a ground plane to reduce electromagnetic interference. Additionally, consider using a ferrite bead or a pi-filter to filter out high-frequency noise.
