DAC91001PFBT Frequently Asked Questions (FAQs)

  • 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.
  • The output voltage settling time can be minimized by using a capacitor (e.g., 10nF) between the output pin and GND. This helps to filter out high-frequency noise and ensures a stable output voltage.
  • The maximum output current of the DAC91001PFBT is 5mA. Exceeding this current may cause the output voltage to droop or the device to overheat.
  • To ensure accurate output voltages, it is recommended to use a high-precision external reference voltage or to calibrate the internal reference voltage using the CAL pin.
  • The CAL pin is used to calibrate the internal reference voltage. To calibrate, connect the CAL pin to a high-precision voltage source (e.g., 2.5V) and then connect the CAL pin to GND. This sets the internal reference voltage to the calibrated value.
