Connection 2

The SM6451AV uses a 1.2 Vrms input reference amplitude. If the input signal is 4 Vrms, then the input must

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

Connection 3

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

tection diodes should be connected to prevent device breakdown.
