Introduction

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 output is also available to drive the shield of a force/sense pair. The AD5520 is available in a 64-lead LQFP package.
