AD5520 General Description
The AD5520 is a single channel per pin parametric measure-ment 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 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 toensure 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.
