DAC8143FSZ

DAC8143 is a 12bit serial-input daisy-chain CMOS D/A converter that features serial data input and buffered serial data output. It was designed for multiple serial DAC systems, where serially daisy-chaining one DAC after another is greatly simplified. The DAC8143 also minimizes address decoding lines enabling simpler logic interfacing. It allows three-wire interface for any number of DACs: one data line, one CLK line and one load line. Serial data in the input register (MSB first) is sequentially clocked out to the SRO pin as the new data word (MSB first) is simultaneously clocked in from the SRI pin. Application includes multiple-channel data acquisition systems, process control and industrial automation, test equipment, remote microprocessor-controlled systems.
