Revision 4 / October 3, 2002
The Edge720 is a totally monolithic ATE pin electronics
solution manufactured in a high-performance
complementary bipolar process.
The three-statable driver is capable of generating 9V
swings over a –1V to +12V range. In addition, 13V super
voltage may be obtained under certain operating
conditions. An input power down mode allows extremely
low leakage current in HiZ. Thus, the Edge720 can help
to eliminate relays that are typically used to isolate devices
such as per pin measurement units from the driver/
comparator/load.
The load supports programmable source and sink currents
of
± 35 mA over a –1V to +12V range, or it can be
completely disabled. In addition, the load is configurable
and may be used as a programmable voltage clamp.
The window comparator spans a 13V common mode
range, tracks input signals with edge rates greater than 6
V/ns and passes sub-ns pulses. An input power down
mode allows for extremely low leakage measurements.
The inclusion of all pin electronics building blocks into a
52 lead QFP (10 mm body w/ exposed heat sink) offers a
highly integrated solution that is traditionally implemented
with multiple integrated circuits or discretes.
The Edge720 is a variant of the Edge710, with the
following improvements:
Reduced D+C+L Leakage Current
Increased Super Voltage Range
Additional VCM_IN buffer reduces the need for
an external buffer when using the load circuit as
a programmable clamp.
