APPLICATION INFORMATION
AC-coupled single-ended configuration
If the application does not require the signal bandwidth to include dc, the level shift shown in Figure 4 is not
necessary.

Figure 22. Single-Ended With Level Shift
Because the signal swing on the op-amp is centered around ground, it is more likely that the signal stays within
the linear region of the op-amp transfer function, thus increasing the overall ac performance.

Compared to the transformer-coupled configuration, the swing on IN– is twice as big, which can decrease the
ac performance (SNR, SFD, and THD).
