EVALUATION BOARD AND SOFTWARE
The evaluation board allows quick testing of the AD8370 by
using standard 50 test equipment. The schematic is shown in
Figure 59. Transformers T1 and T2 are used to transform 50
source and load impedances to the desired input and output
reference levels. The top and bottom layers are shown in
Figure 63 and Figure 64. The ground plane was removed under
the traces between T1 and Pins INHI and INLO to approximate
a 100 characteristic impedance.
The evaluation board comes with the AD8370 control software
that allows serial gain control from most computers. The
evaluation board is connected via a cable to the parallel port of
the computer. Adjusting the appropriate slider bar in the control
software automatically updates the gain code of the AD8370 in
either a linear or linear-in-dB fashion.
