... Both parts have an internal power ON preset that places the wiper in midscale during power-on, which simplifies the fault condition recovery at power-up. In addition, the shutdown SHDN Pin of AD5241/AD5242 places the RDAC in an almost zero power consumption state where Terminal A is open circuited and Wiper W is connected to Terminal B, resulting in only leakage current being consumed in the VR structure ...
