DAC081C085CIMMX/NOPB datasheet by Texas Instruments

DAC081C085CIMMX/NOPB Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC081C085?
  The recommended power-up sequence is to apply VCC first, followed by a delay of at least 100 ns, and then apply the digital supply voltage (VDD). This ensures proper device operation and prevents latch-up.
• How do I ensure accurate output voltage from the DAC081C085?
  To ensure accurate output voltage, it is essential to use a stable reference voltage, minimize noise on the analog input pins, and use a low-noise power supply. Additionally, ensure that the output load is within the recommended range to prevent output voltage droop.
• What is the maximum output current of the DAC081C085?
  The maximum output current of the DAC081C085 is 5 mA. Exceeding this current limit may cause device damage or affect output voltage accuracy.
• Can I use the DAC081C085 with a 3.3V digital supply voltage?
  Yes, the DAC081C085 can operate with a 3.3V digital supply voltage (VDD). However, ensure that the analog supply voltage (VCC) is within the recommended range of 4.5V to 5.5V.
• How do I handle the output voltage settling time of the DAC081C085?
  The output voltage settling time of the DAC081C085 is typically around 10 μs. To ensure accurate output voltage, allow for sufficient settling time before taking measurements or using the output voltage in your application.
