The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC). This ensures that the analog and digital sections of the device are powered up in the correct order.
To ensure accurate voltage output, it is essential to use a high-precision voltage reference (VREF) and to decouple the analog output with a capacitor (e.g., 10nF) to reduce noise and oscillations.
The maximum output current of the DAC7724NB is 10mA. Exceeding this current limit may cause damage to the device or affect its accuracy.
Yes, the DAC7724NB can be used in a ratiometric configuration, where the output voltage is proportional to the reference voltage (VREF). This configuration is useful in applications where the output voltage needs to track changes in the reference voltage.
To minimize noise and glitches, use a low-pass filter (e.g., RC filter) at the output, and ensure that the digital inputs are properly synchronized with the clock signal. Additionally, use a high-quality power supply and decouple the device's power pins.
