The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures proper device operation and prevents latch-up.
To ensure accurate voltage output, it is essential to use a stable reference voltage, minimize noise on the power supply lines, and use a low-noise, low-impedance output load. Additionally, consider using a voltage reference buffer amplifier to further improve accuracy.
The maximum output current capability of the DAC8531E/250 is 5 mA. Exceeding this limit may cause device damage or affect output accuracy.
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 device behavior.
To minimize noise and ensure proper device operation, it is recommended to separate analog and digital signals, use a solid ground plane, and keep sensitive analog signals away from noisy digital signals.
