AC REFERENCE SIGNAL
In some applications, it may be desirable to have ac reference
signals. The AD7225 has multiplying capability within the
upper (VDD 4 V) and lower (2 V) limits of reference voltage
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
VREFA. For input signal frequencies up to 50 kHz, the output
distortion typically remains less than 0.1%. The typical 3 dB
bandwidth figure for small signal inputs is 800 kHz.
