... R-2R ladders, which make up the 12/10 LSBs, respectively. Furthermore, the 4 MSBs are decoded into 15 segments of resistor value 2R. Figure 18 shows the architecture of the 16-bit AD5547. Each of the 16 segments and the R-2R ladder carries an equally weighted current of one-sixteenth of full scale. The feedback resistor R and 4-quadrant resistor R have values of 10 kΩ ...

... AD5547/AD5557 REFERENCE SELECTION When selecting a reference for use with the AD55xx series of current output DACs, pay attention to the output voltage, temperature coefficient specification of the reference. Choosing a precision reference with a low output temperature coefficient minimizes error sources. Table 10 lists some of the references available from Analog Devices, Inc ...
