MEASUREMENT SETUP
The basic board connections for measuring bandwidth are
shown in
Figure 4. A 5 V, 200 mA (minimum) power supply is
required, and a low noise voltage reference supply is required
for VGAIN.
BOARD LAYOUT AND PARTS LIST
The evaluation board circuitry uses four conductor layers. The
two inner layers are ground, and all interconnecting circuitry is
located on the outer layers.
Figure 5, Figure 6, Figure 7, Figure 8,
and
Figure 9 illustrate the copper patterns, and Table 2 is a
parts list.
