AD5520JSTZ

Per Pin Parametric Measurement Unit/Source Measure Unit AD5520 FEATURES GENERAL DESCRIPTION Force/measure functions The AD5520 is a single-channel, per pin parametric measure- FIMV, FVMI, FVMV, FIMI, FNMV ment unit (PPMU) for use in semiconductor automatic Force/measure voltage range 11 V test equipment. The part is also suited for use as a source 4 user programmable force/measure current ranges measurement unit for instrumentation applications. It 4 A, 40 A, 400 A, 4 mA (external resistors) contains programmable modes to force a pin voltage and 2 user programmable extended current ranges measure the corresponding current, or force a current and Up to 6 mA without external driver measure the voltage. The AD5520 can force/measure over a Higher currents with external driver 11 V range or user-programmable currents up to 4 mA Clamp circuitry and window comparators on board with its on-board force amplifier. An external amplifier is Guard amplifier required for wider current ranges. The device provides a force 64-lead LQFP package sense capability to ensure accuracy at the tester pin. A guard output is also available to drive the shield of a force/sense pair. APPLICATIONS The AD5520 is available in a 64-lead LQFP package.
