AD5546/AD5556 CIRCUIT OPERATION DIGITAL-TO-ANALOG (DAC) CONVERTER SECTION The AD5546/AD5556 are 16-/14-bit multiplying, current out- put, and parallel input DACs. The devices operate from a single 2 5.5 V supply and provide both unipolar –V 0 ...
Page 11
DIGITAL SECTION The AD5546/AD5556 have 16-/14-bit parallel inputs. The devices are double buffered with 16-/14-bit registers. The double-buffered feature allows the update of several AD5546/AD5556 simultaneously. For the AD5546, the input register is loaded directly from a 16-bit controller bus ...
