The SM6451A uses a 1.2Vrms input reference amplitude. If the input signal is 4Vrms, then the input must be

reduced by a factor of 1/3.3, and the output increased by a factor of 3.3.

When there is a possibility that the input peak-to-peak amplitude will exceed the supply voltage, input protec-

tion diodes should be connected to prevent device breakdown.
