EVALUATION BOARDS

The AD8337 evaluation boards provide a family of platforms for

testing and evaluating the AD8337 VGA. Three circuit configu-

rations are available:



AD8337-EVALZ, dc-coupled, with noninverting gain and

dual power supplies



AD8337-EVALZ-INV, dc-coupled, with inverting gain and

dual power supplies



AD8337-EVALZ-SS, ac-coupled, with noninverting gain

configuration and a single supply

These fully assembled and tested boards are ready to use. Only

the appropriate power supply and signal source connections

need to be made. SMA connectors are provided for the pream-

plifier and VGA outputs. Photos of fully assembled boards are

shown in Figure 76 and Figure 77. The board component side

layouts are shown in Figure 78 and Figure 79.

Schematic diagrams of the dual-supply board for noninverting

and inverting configurations are shown in Figure 80 and Figure 81.

The dual-supply boards require ±2.5 V to ±5 V supplies capable of

supplying 20 mA or greater. A schematic diagram of the single-

supply board is shown in Figure 82. The single-supply version

accepts a +5 V to +10 V supply with 20 mA or greater capability.
