The AD7836ASZ is a quad 14-bit Digital-to-analog Converter (DAC) on one monolithic chip. It has output voltages with a full-scale range of ±10V from reference voltages of ±5V. The AD7836 accepts 14-bit parallel loaded data from the external bus into one of the input latches under the control of the WR, CS and DAC channel address pins, A0-A2. The DAC outputs are updated individually, on reception of new data. In addition, the SEL input can be used to apply the user programmed value in DAC Register E to all DAC, thus setting DAC output voltages to the same level. The contents of the DAC data registers are not affected by the SEL input. The DAC output is buffered with a gain of two amplifiers into which an external DAC offset voltage can be inserted via the DUTGNDx pins.
