(1)

The 1N and 2N naming convention is used to indicate the number of PWM lines to the power stage per channel in a specific mode.

(2)

Using 1N interface in BTL and PBTL mode results in increased DC offset on the output terminals.

(3)

The 4xSE mode can be used as 1xBTL + 2xSE configuration by feeding a 2N PWM signal to either INPUT_AB or INPUT_CD for

improved DC offset accuracy
