Working Principles

The AD734AN operates by converting digital input data into corresponding analog output voltages. The digital input data is provided through the D0-D7 pins, representing the desired output voltage levels. The internal circuitry then converts this digital information into analog voltages, which are available at the VOUT1-VOUT4 pins. The reference voltages (VREF1-VREF4) determine the maximum output voltage range.
