To reduce voltage loss by the wire
resistance in maximum output, it

GND:
It is GND pin for the speaker

Pin

is for L-channel
Because the big electric current
flows, it is desirable to separate from
the GND line to the other GND pin
on the board pattern. Also, it isn't
connected with the substrate potential
in the IC.

Audio signal automatic detection
distinction output:
It outputs the distinction result of
the audio signal automatic detection
circuit.
The output form is the open collector
output from of the NPN transistor.
Therefore, the pull rises and uses for
the power by the external resistance
(equal to or more than
