The recommended power-up sequence is to apply VDD first, followed by VREF, and then the digital supply (VCC). This ensures that the internal reference voltage is stable before the DAC starts operating.
The DAC8163 has a rail-to-rail output stage, but it's not guaranteed to swing all the way to the supply rails. To ensure maximum output range, use an external op-amp to buffer the output and provide additional gain if needed.
The maximum update rate of the DAC8163 is 1 MSPS (million samples per second), but this can be limited by the interface clock frequency and the specific application. Consult the datasheet for more information on update rates and interface timing.
The internal reference voltage of the DAC8163 can be bypassed with an external reference voltage if desired. However, if using the internal reference, ensure that the VREF pin is properly decoupled with a capacitor to reduce noise and improve performance.
The typical settling time of the DAC8163 is around 2.5 μs, but this can vary depending on the output voltage range, load capacitance, and other factors. Consult the datasheet for more information on settling time and output characteristics.
