AC REFERENCE SIGNAL
In some applications, it may be desirable to have ac reference
signals. The AD7225 has multiplying capability within the
upper (V
when operated with dual supplies. Therefore, ac signals need to
be ac-coupled and biased up before being applied to the
reference inputs. Figure 19 shows a sine wave signal applied to

bandwidth figure for small signal inputs is 800 kHz.
