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 μA, ±40 μA, ±400 μA, ±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
