... When shutdown is returned to logic-high the previous latch settings put the wiper in the same resistance set- ting prior to shutdown. The AD5203 is available in a narrow body P-DIP-24, the 24-lead surface mount package, and the compact 1.1 mm thin TSSOP-24 package. All parts are guaranteed to operate over the extended industrial temperature range of – ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD5203 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... AD5203. The exact timing requirements are shown in Figure 1. The AD5203 resets to a midscale by asserting the RS pin, sim- plifying initial conditions at power-up. Both parts have a power shutdown SHDN pin that places the RDAC in a zero power consumption state where terminals Ax are open-circuited and the wiper Wx is connected to Bx, resulting in only leakage cur- rents being consumed in the VR structure ...
