Example 1: Dual differential inputs
In the case where the distance between the TS4962M outputs and speaker terminals is
high, it is possible to have low frequency EMI issues due to the fact that the typical operating
frequency is 250kHz. In this configuration, we recommend using an output filter (as shown
in
possible to the device.
