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 correctly.
To ensure accurate voltage output, it is essential to use a high-precision voltage reference, such as the REF5025 or REF5030, and to follow proper PCB layout and design guidelines to minimize noise and interference.
The maximum output current of the DAC8164 is 10 mA per channel. Exceeding this current limit can cause damage to the device or affect its accuracy.
To synchronize multiple DAC8164 devices, use the SYNC pin to synchronize the internal clock of each device. This ensures that the devices update their outputs simultaneously, which is essential in applications requiring coordinated output signals.
The CLR (Clear) pin is used to reset the DAC8164 to its power-on state. When the CLR pin is asserted low, the device resets its internal registers and output voltage to zero, allowing for a controlled startup sequence.
