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 analog input pins, and use a low-noise power supply. Additionally, consider using a voltage reference buffer amplifier to reduce the output impedance.
The maximum clock frequency that the DAC084S085CIMM can handle is 40 MHz. Exceeding this frequency may result in incorrect data conversion or device malfunction.
During power-down or reset, the DAC084S085CIMM's output may go to an undefined state. To prevent this, use an external buffer amplifier or a voltage follower to hold the output voltage stable until the device is fully powered up or reset.
To minimize noise and ensure proper device operation, it is recommended to keep analog and digital signal traces separate, use a solid ground plane, and place decoupling capacitors close to the device's power pins.
