Features
E737
Per-Pin Precision
Measurement Unit
The E737 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.
The E737 supports two modes of operation: force cur-
rent/measure voltage and force voltage/measure cur-
rent. The E737 can force or measure voltage in the
range of -5V to +7V. In addition, the E737 can force
or measure a current of up to 40 mA over four distinct
ranges: ±40 mA, ±1 mA, ±100 µA and ±10 µA.
• FV / MI Capability
• FI / MV Capability
• 4 Current Ranges (±40 mA, ±1 mA, ±100 µA,
±10 µA)
• -5V/+7V I / O Range
• Short Circuit Protection
• Clamps for limiting mode and range select
transients
The E737 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 pro-
portional to either the DUT voltage or current.
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.
Applications
• Automatic Test Equipment
- Memory Testers
- VLSI Testers
- Mixed Signal Tester
The E737 is designed to be a low power, low cost,
small footprint solution to allow high pin count testers
to support a PMU per pin.
