TS4962M
Application information
33/41
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 Figure 1: Typical application schematics on page 4). It should be placed as close as
possible to the device.
