GENERAL DESCRIPTION

The AD5329 is a serial-input, dual 12-bit digital-to-analog converter that accepts two’s complement digital coding. An internal voltage reference generates a stable 2V DACREF. The buffered DACREF output generates the system bipolar ground reference at pin VBZ. The bipolar DAC output swing programs over a 4VPP range. The device is specified for operation from +5 volts ±10.
