... Multiplying DACs with Four-Quadrant Resistors DB0 TO DB15 = 10 V GENERAL DESCRIPTION The AD5546/AD5556 are precision 16-/14-bit, multiplying, low power, current output, parallel input digital-to-analog converters (DACs). They operate from a single 2 5.5 V supply with ±10 V multiplying references for four-quadrant outputs. Built- in four-quadrant resistors facilitate the resistance matching and temperature tracking that minimize the number of components needed for multiquadrant applications ...

... 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 when the WR pin is brought low. The DAC register is updated with data from the input register when LDAC is brought high ...
