S30011

The level shift changes the direction of the current(lconv) as the same amount, and then supply it to the power AMP.

The resistor Ra(21K) converts current into voltage with the DC offset of Pref.

The power amp has unity gain.

So the total differential voltage gain of the S30011 is as follows.

If you want to reduce the total gain of the BTL drive part, use additional series resistor into the input pin(pin#3, 10, 19, 25)

You can also increase or decrease the voltage gain of the CH1, CH4 using adjustable pin(pin#4, pin24) by inserting an external

series resistor.
