AD5547/AD5557 CIRCUIT OPERATION DAC SECTION The AD5547/AD5557 are 16-/14-bit, multiplying, current- output, parallel input DACs. The devices operate from a single 2 5.5 V supply and provide both unipolar ( – ...
Page 13
DIGITAL SECTION The AD5547/AD5557 have 16-/14-bit parallel inputs. The devices are double buffered with 16-/14-bit registers. The double buffered feature allows the simultaneous update of several AD5547s/ AD5557s. For the AD5547, the input register is loaded directly from a 16-bit ...
