FEATURES Force/measure functions FIMV, FVMI, FVMV, FIMI, FNMV Force/measure voltage range ±11 V 4 user programmable force/measure current ranges ±4 μA, ±40 μA, ±400 μA, ±4 mA (external resistors) 2 user programmable extended current ranges Up to 6 mA without external driver Higher currents with external driver Clamp circuitry and window comparators on board Guard amplifier 64-lead LQFP package APPLICATIONS Automatic test equipment Per pin PMU, shared pin PMU, device power supply instrumentation Source measure, parametric measurement, precision measurement 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 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.
