TDA7418
Description of the audioprocessor
4.11
MUX output
It provides a mono signal output (before tone filters) at Mute/MUX pin, used for external level
meter / spectrum analyzer.
The mute pin can be configured as MUX output (I2C Byte13_D7D1). When it is configured
as MUX output, the output voltage is (InGainL+InGainR)/2 with -3dB attenuation.
Figure 18.
MUX output configuration
4.12
Audioprocessor testing
In the test mode, which can be activated by setting bit D7 of the IIC subaddress byte and bit
D0 of the testing audioprocessor byte, several internal signals are available at the SE2R pin.
In this mode, the input resistance of 100kOhm is disconnected from the pin. Internal signals
available for testing are listed in the data-byte specification.

InGainL
InGainR
MUTE/MUX = (InGainL+InGainR)/2 * (-3dB)
