Features

Description

The Edge737 is a precision measurement unit designed

for automatic test equipment and instrumentation.

Manufactured in a wide voltage CMOS process, it is a

monolithic solution for a per pin PMU.

• FV / MI Capability

• FI / MV Capability

• 4 Current Ranges (± 40 mA, ± 1 mA, ± 100 µA,

± 10 µA)

• + 7V / –5V I / O Range

• Short Circuit Protection

• Clamps for limiting mode and range select transients

The Edge737 supports two modes of operation: force

current/measure voltage and force voltage/measure

current. The Edge737 can force or measure voltage in

the range of + 7V to –5V. In addition, the Edge737 can

force or measure a current of up to 40 mA over four distinct

ranges: ± 40 mA, ± 1 mA, ± 100 µA and ± 10 µA.

Applications

The Edge737 has an on board window comparator that

provides three bits of information: DUT too high, DUT too

low, and DUT fail. There is also a monitor function which

provides a real time analog voltage signal proportional to

either the DUT voltage or current.

•

Automatic Test Equipment

- Memory Testers

- VLSI Testers

- Mixed Signal Tester

On board clamps prevent large transient spikes when

changing operating mode or current range. Also, the PMU

will survive a direct short over the legal voltage range.

The Edge737 is designed to be a low power, low cost,

small footprint solution to allow high pin count testers to

support a PMU per pin.
