5. Hi-Z mode
This is built in a high impedance mode of amplifier output.
When this function is operated, HP_EN of resister 1 is set "0” and Hi-Z of resister 3 is set “1”.
6. SGND
This terminal is used when it is combined as an
FM tuner antenna and the headphone GND.

In case of this connection, the separation
OUTL
characteristic becomes bad by inductor.
But this IC can prevent deterioration of separation
OUTR
by a connection of Figure 6.

Timing charts may be simplified for explanatory purpose.
These protection functions are intended to avoid some output short circuits or other abnormal conditions
temporarily. These protect functions do not warrant to prevent the IC from being damaged.
In case of the product would be operated with exceeded guaranteed operating ranges, these protection features may
result in the IC being damaged.
The over current protection feature is only intended to protect the IC from a temporary short circuit.
Long time short circuit may stress excessively on the IC to be damaged. The system must be configured so that any
over current condition will be eliminated as soon as possible.
