APPLICATIONS INFORMATION
The AD8260 is ideally suited for compact applications requiring
high frequency and large current drive of complex modulation
products. Because the driver is capable of providing up to 300 mA
(using a 3.3 V supply rail) to very low impedance loads, undefined
network impedances are of little consequence. Such applications
can include, but are not limited to, local power line wiring
found in homes or in automobiles, or low impedance complex
filters used in communications. Pulse response performance
with loading effects are illustrated by various curves in the
Typical Performance Characteristics section.
Figure 65 is an application block diagram showing AD8260
devices configured as transceivers in a small local network.
In this figure, consider a small security system consisting of a
master controller and four satellite cameras. For example, the
master can be a processor-controlled switch that routes data to
and from local satellite cameras. The cameras video signals are
modulated for transmission over an existing power system such
as the wiring found in homes or small businesses. Using the
existing power network in this way eliminates the need to install
additional cabling, thereby saving cost. Portability is also
achieved because the system can be moved to other locations
should the need arise, simply by unplugging a satellite and
moving it elsewhere. The AD8260 transceivers perform the
same function at the master and slave locations; a high frequency
current-output DAC converts digital-to-analog data for the
high current driver for transmission over a low impedance load.
The input of the VGA/preamplifier connects to the same load,
functioning as the receiver. In such a system, multiple AD8260
devices are connected to form a network, much like a LAN,
except using the power-line wiring in a home or automobile in
lieu of a CAT-5 cable, for example.

Figure 65. AD8260 Transceiver Application
Figure 66 shows the AD8260 as a low distortion, high power
driver. The VGA and high current driver are combined by
simply connecting the differential output of the VGA directly to
the input of the driver.
