Product specification
TDA9605H
7.5.3 NORMAL INPUT LEVEL
Fifteen settings of amplification and mute can be selected for the linear audio input signal on pin LININ. The normal input
level control can replace the manual adjustment of the playback level at the linear audio circuit.
All selections using the normal linear audio signal include the normal input level control.

7.6 Input byte at subaddress 02H
The input byte is used for input selection of the hi-fi and linear audio.
7.6.1 INPUT SELECT
The input select function defines the input signal which is forwarded to the volume control function of hi-fi processing and
usually via the normal select function to the external linear audio circuit on pin LINOUT.
