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 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.
