Preliminary Technical Data
TYPICAL APPLICATION FOR THE AD5522
Figure 29 shows the AD5522 as used in an ATE system. This
device can used as a per pin parametric unit in order to speed
up the rate at which testing can be done.
The central PMU shown in the block diagram is usually a
highly accurate PMU, and is shared among a number of pins in
the tester. In general, many discrete levels are required in an
ATE system for the pin drivers, comparators, clamps, and active
loads. DAC devices, such as the AD5379, offer a highly
integrated solution for a number of these levels. The AD5379 is
a dense 40-channel DAC designed with high channel
requirements, such as ATE
