The AD7841 contains eight 14-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 AD7841 accepts 14-bit parallel loaded data from the external bus into one of the input registers under the control of the WR, CS and DAC channel address pins, A0A2. The DAC outputs are updated on reception of new data into the DAC registers. All the outputs may be updated simultaneously by taking the LDAC input low.
