Data Sheet

The following code provides a macro model net list for the

10 kΩ RDAC:

RDAC CIRCUIT SIMULATION MODEL

The internal parasitic capacitances and the external load

dominates the ac characteristics of the RDACs. The −3 dB

bandwidth of the AD5231BRU10 (10 kΩ resistor) measures

370 kHz at half scale when configured as a potentiometer

divider. Figure 15 provides the large signal BODE plot charac-

teristics. A parasitic simulation mode is shown in Figure 57.
