3. Mode selection
In the VX32L LCD TV TDA8946AJ has two functional modes, which can be selected by applying
the proper DC voltage to pin MODE.
1. 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).
2. Operating — In this mode the amplifier is operating normally. The operating mode is activated at
VMODE<1.0V.
