DAC61408RHAR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by VREF, and then the digital inputs. This sequence helps prevent unwanted outputs during power-up.
  • To ensure accurate output voltage levels, make sure to use a low-impedance reference voltage source, and decouple the VREF pin with a capacitor (e.g., 10nF) to reduce noise. Additionally, use a stable and low-noise power supply for VDD.
  • The maximum output current of the DAC61408RHAR is 5mA per channel. Exceeding this limit may cause output voltage errors or even damage the device.
  • The output voltage settling time of the DAC61408RHAR is typically around 10μs. To ensure accurate readings, wait for at least 10μs after updating the DAC register before taking a measurement.
  • Yes, the DAC61408RHAR can be used in a ratiometric configuration, where the output voltage is proportional to the reference voltage. This configuration can be useful in applications where the output voltage needs to track changes in the reference voltage.
