EVALUATION BOARD

Figure 17 shows the schematic of the ADL5322 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 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 17 for proper

operation.
