Edge737
Per-Pin Precision
Measurement Unit
TEST AND MEASUREMENT PRODUCTS
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.
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 鈥?V. In addition, the Edge737 can
force or measure a current of up to 40 mA over four distinct
ranges:
鹵
40 mA,
鹵
1 mA,
鹵
100
碌A(chǔ)
and
鹵
10
碌A(chǔ).
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.
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.
