Working Principles

The DAC7800LP operates by converting digital input data into an analog voltage output. It utilizes a 12-bit resolution to provide high precision and accuracy. The digital data is received through the DB15 to DB0 pins, and the converter internally converts it into an analog voltage based on the supplied reference voltage (REF IN). The resulting analog voltage is available at the VOUT pin.
