64-lead LQFP package The AD5520 is a single-channel, per pin parametric measurement unit (PPMU) for use in semiconductor automatic
test equipment. The part is also suited for use as a source
measurement unit for instrumentation applications. It
contains programmable modes to force a pin voltage and
measure the corresponding current, or force a current and
measure the voltage. The AD5520 can force/measure over a
±11 V range or user-programmable currents up to ±4 mA
with its on-board force amplifier. An external amplifier is
required for wider current ranges. The device provides a force
sense capability to ensure accuracy at the tester pin. A guard …
