Evaluation Board

Figure 13 is a schematic of an evaluation board available for the

AD8225. The board is shipped with an AD8225 already installed

and tested. The user need only connect power and an input to

conduct measurements. The supply may be configured for dual

or single supplies, and the input may be dc- or ac-coupled. A

circuit is provided on the board so that the user can zero the

output offset. If desired, a reference may be applied from an

external voltage source.
