The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the internal voltage regulators are powered up correctly.
To ensure accurate voltage output, it is recommended to use a high-precision voltage reference, such as the Texas Instruments REF5025. Additionally, the DAC output should be filtered using a low-pass filter to remove any noise and glitches.
The maximum output current of the DAC8234SPFB is 5mA per channel. Exceeding this current limit may cause damage to the device or affect its accuracy.
To synchronize multiple DAC8234SPFB devices, connect the SYNC pin of each device together and drive it with a common clock signal. This ensures that all devices update their outputs simultaneously.
The LDAC (Load DAC) pin is used to update the DAC output. When LDAC is low, the DAC output is updated with the new data. When LDAC is high, the DAC output is latched and does not change.
