CONFIGURATIONS
The AD8274 can be configured in several ways; see Figure 40 to Figure 47. Because these configurations rely on the internal, matched
resistors, all of these configurations have excellent gain accuracy and gain drift. Note that the AD8274 internal op amp is stable for noise
gains of 1.5 and higher, so the AD8274 should not be placed in a unity-gain follower configuration.
