4.AUX. input (pin(16))
The pin(16) is for input terminal of AUX. amplifier.
The total gain is 0dB by using of AUX. amplifier.
Therfore, the COM can directly drive the AUX. amplifier.
Beep sound or voice synthesizer signal can be input to pin(16) directly.
5. Diagnosis output (pin(25))
The diagnosis output terminal of pin(25) has open collector output structure on clip as shown in Fig.7.
In unusual case that output terminal of power amp. is condition of output to VCC or output to GND short and
over voltage input mode, it is possible to protect all the system of apparatus as well as power IC protection.
In case of being unused this function, use this IC as openconnection on pin(25).
