Description

The AD7839 contains eight 13-bit DACs on one monolithic chip. It has output voltages with a full-scale range of ±10 V from reference voltages of ±5 V.The AD7839 accepts 13-bit parallel loaded data from the external bus into one of the input registers under the control of theWR,CSand DAC channel address pins, A0–A2.The DAC outputs are updated on reception of new data into the DAC registers. All the outputs may be updated simultaneously by taking theLDACinput low.Each DAC output is buffered with a gain-of-two amplifier into which an external DAC offset voltage can be inserted via the DUTGNDx pins.The AD7839 is available in a 44-lead MQFP package.
