THEORY OF OPERATION The AD5520 is a single-channel per pin parametric measure- ment unit (PPMU) for use in semiconductor automatic test equipment. It contains programmable modes to force a pin voltage and measure the corresponding current (FVMI), force current measure ...
Page 14
AD5520 INTERFACE The AD5520 PPMU is controlled via a number of digital inputs, which are discussed in detail in the following sections. All inputs are TTL-compatible used to select the device while STB (active low input) latches data ...

AD5520 CIRCUIT OPERATION FORCE VOLTAGE Most PMU measurements are performed while in force voltage and measure current modes; for example, when the device is used as a device power supply continuity or leakage testing. In the force voltage ...
Page 17
FORCE CURRENT In force current mode, the voltage at FIN is now converted to a current through the following relationship: Force Current = V /(R × 16) FIN SENSE Figure 24 shows a simplified diagram of the PMU when in ...
