Edge4707B

Quad Channel Per-Pin

Precision Measurement Unit

TEST AND MEASUREMENT PRODUCTS

Features

Description

The Edge4707B 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 quad channel per pin PMU.

4 Current Ranges (2 µA, 20 µA, 200 µA, 2mA)

–2V to + 13V Output Range (Zero Current)

0V to 11V Output Range (Full Scale Current)

FV Linearity to ± .025% FSR

Central PMU Switches

Each channel of the Edge4707B features a PMU that can

force or measure voltage over a 15V I/O range, and

supports 4 current ranges: 2 µA, 200 µA, 20 µA, and 2

mA.

Per Pin Super Voltage Switches

Each channel of the Edge4707B features an on-board

window comparator that provides two bits of information:

DUT too high and DUT too low. There is also a monitor

function which provides a real time analog signal

proportional to either the measured voltage or current.
