DAC8234SPFBR Frequently Asked Questions (FAQs)

  • The recommended output load impedance is 1 kΩ or higher to ensure optimal performance and to prevent output voltage droop.
  • The internal reference voltage can be configured by connecting the REFSEL pin to VCC (for 2.5V reference) or to GND (for 1.25V reference). Additionally, an external reference voltage can be used by connecting it to the REFIN pin.
  • The maximum update rate for the DAC output is 1 MSPS (million samples per second) in asynchronous mode and 2 MSPS in synchronous mode.
  • The POR and BOR features can be handled by connecting the POR pin to VCC through a pull-up resistor and the BOR pin to GND through a pull-down resistor. This ensures that the device resets properly during power-on and brown-out conditions.
  • It is recommended to use a 10 μF ceramic capacitor in parallel with a 100 nF ceramic capacitor to decouple the power supply (VCC) and to reduce noise and ripple.
