Per-pin Parametric Measurement Unit / Source Measure Unit
The AD5520 is a single channel Per pin Parametric Measurement Unit (PPMU) for use in semiconductor automatic test equipment and precision measurement instruments. It contains programmable modes to force a pin voltage and measure the corresponding current or force a current and measure the voltage. The PPMU can force a voltage from -11 V to +11 V or currents up to ±4 mA. 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.
