DAC811KU Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC). This ensures that the analog circuitry is powered up before the digital circuitry.
  • To ensure accurate voltage output, it is essential to use a stable reference voltage, minimize noise on the analog input pins, and use a low-noise power supply. Additionally, the output voltage should be buffered with an op-amp to prevent loading effects.
  • The maximum output current of the DAC811KU is 5 mA. Exceeding this current limit can cause damage to the device or affect its accuracy.
  • The DAC811KU's digital interface is a 3-wire serial interface. The SCLK pin is the clock input, the SDIN pin is the data input, and the SYNC pin is the chip select input. The interface operates in SPI mode, and the clock frequency should not exceed 50 MHz.
  • The internal reference voltage is used to set the full-scale output voltage of the DAC. The internal reference voltage is 2.5 V, which corresponds to a full-scale output voltage of 2.5 V. The internal reference voltage can be bypassed by connecting an external reference voltage to the VREF pin.
