AD7849ARZ

AD7849 is a 14-bit serial input multiplying digital to-analogue converter (DAC). It has a versatile serial interface structure and can be controlled over three lines to facilitate opto-isolator applications. SDOUT is the output of the on-chip shift register and can be used in a daisy-chain fashion to program devices in the multichannel system. The daisy-chain enable (DCEN) input controls this function. The BIN/COMP pin sets the DAC coding; with BIN/COMP set to 0, the coding is straight binary; and with BIN/COMP set to 1, the coding is twos complement. This allows the user to reset the DAC to 0V in both the unipolar and bipolar output ranges. It is widely used in application such as industrial process controls, PC analogue I/O boards, instrumentation etc.
