3. Mode selection

In the L32 LCD TV TDA8946AJ has two functional modes, which can be selected by applying
the proper DC voltage to pin MODE.

a. Mute —

In this mode the amplifier is DC-biased but not operational (no audio output).

This allows the input coupling capacitors to be charged to avoid pop-noise. The device is in
mute mode when 3.5 V < VMODE < (VCC 1.5 V).

b. Operating — In this mode the amplifier is operating normally. The operating mode is
activated at VMODE<1.0V.
