Data Sheet
EVALUATION BOARD
Figure 41 shows the schematic of the AD8354 evaluation board.
Note that L1 is shown as an optional component that is used to
obtain maximum gain only when VP = 3 V. The board is powered
by a single supply in the 2.7 V to 5.5 V range. The power supply
is decoupled by a 0.47 µF and a 100 pF capacitor.
