Description
Edge4707B
Quad Channel Per-Pin
Precision Measurement Unit
Features
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.
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.
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.
The Edge4707B is designed to be a low power, low cost,
small footprint solution to allow high pin count testers to
support a PMU per pin.
In addition, two independent switches per channel (for a
central PMU force and sense) plus two wide voltage analog
muxes per channel are included.
