The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly.
To ensure accurate voltage output, it is essential to use a low-noise, low-impedance voltage reference, and to decouple the output with a capacitor to reduce noise and oscillations.
The maximum output current of the DAC712P is 10 mA. Exceeding this current may cause damage to the device or affect its accuracy.
Yes, the DAC712P can be used in a ratiometric configuration, where the output voltage is proportional to the reference voltage. This can be useful in applications where the output voltage needs to track changes in the reference voltage.
During power-down or reset, it is recommended to keep the digital inputs in a high-impedance state or pull them up to a valid logic level to prevent unwanted output voltage transitions.
