... 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 AD5520 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 ...

... PMU—which measure mode it is in, which com- pensation capacitor is used, and the selected current range. Standby Mode The AD5520 may be placed into standby mode via the standby logic input. In this mode, the force amplifier is disconnected from the force input (FIN), the switch in series with the force output pins, FOHx, is opened, and the current measure amplifier is dis- connected from the sense resistors ...

... High High Standby (same as STANDBY = High) R Selection S The AD5520 is designed so that the voltage drop across each of resistors will be less than ±500 mV when maximum current the flowing through them. To support other current ranges, these sense resistor values may be changed. A force amplifier can drive a maximum ...

... AD5520 TYPICAL APPLICATION CIRCUIT Figure 9 shows the AD5520 as it would be used in an ATE system. This device could be used as a per pin parametric unit in order to speed up the rate at which testing could be done. It could also be used as a DUT power supply, as shown in the application circuit. The central PMU shown in the block diagram is usually a highly accurate PMU and is shared among a number of pins in the tester ...
