Evaluation Board for the AD8337 VGA INTRODUCTION The AD8337 is a versatile variable gain amplifier (VGA); therefore, the evaluation board should be just as versatile. The board is offered in three configurations: noninverting, inverting, and single supply (noninverting). These variations enable the user to quickly become familiar with the many operating characteristics and features of the AD8337 ...

... Figure 7. Evaluation Board Schematic—Single-Supply Version OUTPUT PROTECTION The AD8337 VGA output stage is specified for driving loads of 500 Ω or greater. To protect the stage from accidental overload, a 453 Ω resistor is provided which, when connected to 50 Ω test equipment inputs, enables safe operation. In certain high load impedance situations, the user can reduce the value of this resistor ...

... For ease of assembly, all board components are located on the primary side and all are 0603 size surface mounts. Higher density applications can require components on both sides of the board and present no problem to the AD8337, as demonstrated in unreleased versions of the board that featured secondary-side components and vias. Not evident in the figures are thermal vias within the pad that solder to the mating pad of the AD8337 chip-scale package ...
