... The ADA4932-x behaves much like a standard voltage feedback op amp and facilitates single-ended-to-differential conversions, common-mode level shifting, and amplifications of differential signals. Like an op amp, the ADA4932-x has high input impedance and low output impedance. Because it uses voltage feedback, the ADA4932-x manifests a nominally constant gain bandwidth product ...

... G Terminating a Single-Ended Input This section describes how to properly terminate a single-ended input to the ADA4932-x with a gain 499 Ω. An example using an input source with a terminated output voltage p-p and source resistance of 50 Ω illustrates the four steps that must be followed. Note that because the terminated output voltage of the source p-p, the open-circuit output voltage of the source p-p ...

... ADA4932-1/ADA4932-2 LAYOUT, GROUNDING, AND BYPASSING As a high speed device, the ADA4932-x is sensitive to the PCB environment in which it operates. Realizing its superior performance requires attention to the details of high speed PCB design. The first requirement is a solid ground plane that covers as much of the board area around the ADA4932-x as possible. However, ...
