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 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. FUNCTIONAL BLOCK DIAGRAM COMPOUT0 COMPOUT1 COMPOUT2 COMPIN0 COMPIN1 COMPIN2 AVEE AVCC AD5520 FOH FOH3 FO...
