AD7839ASZ

The AD7839 integrates eight 13-bit voltage output DACs on a single chip. It uses a ±5 V reference voltage and an output voltage full-scale range of ±10 V. There are three independent differential reference voltages: one for DACs A and B, one for DACs G and H, and one for DAC C, D, E, and F. Under the control of active-low WR, active-low CS, and DAC address pins A0–A2, the AD7839 loads 13-bit parallel data from the external bus into one of the input latches. When the DAC registers receive new data, the DAC output is updated. Each DAC output is buffered with a gain 2 amplifier, and an external DAC offset voltage can be inserted into the amplifier via the DUTGND pin. The AD7839 is available in a 44-lead PQFP package.
