EVALUATION BOARD
Figure 18 shows the schematic of the ADL5323 evaluation
board. The board is powered by a single supply in the 4.75 V to
5.25 V range. The power supply is decoupled on each of the
three power supply pins by 10 μF, 10 nF, and 100 pF capacitors.
See Table 5 for the exact evaluation board component values.
Note that all three VCC pins (Pin 1, Pin 2, and Pin 5) should be
independently bypassed as shown in Figure 18 for proper
operation.
