The AD7840 is a fast, complete 14-bit voltage output D/A converter. It consists of a 14-bit DAC, 3V buried Zener reference, DAC output amplifier, and high-speed control logic. The part features double-buffered interface logic with a 14-bit input latch and 14-bit DAC latch. Data is loaded to the input latch in either of two modes, parallel or serial. This data is then transferred to the DAC latch under control of an asynchronous LDAC signal. A fast data setup time of 21ns allows direct parallel interfacing to digital signal processors and high-speed 16-bit microprocessors. In the serial mode, the maximum serial data clock rate can be as high as 6MHz. The analog output from the AD7840
