ULTRASOUND TGC APPLICATION
The
industrial ultrasound applications. The TGC amplifier is a key
subsystem in such applications because it provides the means
for echo location of reflected ultrasound energy.
Figure 91 through Figure 93 are schematics of a dual, fully
differential system using the AD8332 and the
high speed ADC with conversion speeds as high as 65 MSPS.

HIGH DENSITY QUAD LAYOUT
The
board space. Figure 94 represents four channels routed to and
away from this very compact quad VGA. Note that none of the
signal paths crosses and that all four channels are spaced apart
to eliminate crosstalk.
In this example, all of the components shown are 0402 size;
however, the same layout is executable at the expense of slightly
more board area. The sketch also assumes that both sides of the
printed circuit board are available for components and that the
bypass and power supply decoupling circuitry is located on the
wiring side of the board.
AD8334
is the ideal solution for applications with limited
