ADA4096-2 & the Filter Wizard

Hi,

 

After using the filter wizard for a design, I am finding some ambiguity in the results of the software, vs data sheet specifications. Or probably a misunderstanding on the results on my part.

 

The ADA4096 data sheet indicates an input overload swing of +/-32 Vpp. However, when selecting this part at the front end of an active filter design, when viewing "Voltage Range", it indicates a maximum input of 50mVpp, and 33mVpp nominal.

 

Are these numbers with respect to boundaries of filter performance, or input voltage that may damage the amplifier? The filter is a 40dB gain, 7th order Chebyshev. A, B stage = ADA4096, C,D stage = ADA4051.

 

Regards and thanks.
