The maximum output current of the DAC8574IPWR is 5mA per channel.
To ensure monotonicity, use a clock frequency of at least 10 times the update rate, and ensure that the output voltage is not loaded with a capacitance greater than 100nF.
The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC).
To enter power-down mode, set the PD pin low. In power-down mode, the DAC output is high-impedance, and the device consumes minimal power.
The maximum clock frequency for the DAC8574IPWR is 50MHz.
