- AUX Input (pin 16) The pin 16 is for input terminal of AUX amplifier. The total gain is 0dB by using of AUX amplifier. Therefore, the /G6d-COM can directly drive the AUX amplifier. BEEP sound or voice synthesizer signal can be input to pin 16 directly. When AUX function is not used, this pin must be connected to PRE-GND (pin 13) via a capacitor. 5. Diagnosis Output (pin 25) This diagnosis output terminal of pin 25 has open collector output structure on chip as shown in Figure 7. In case diagnosis circuit that detect unusual case is operated, NPN transistor (Q1) or (Q2) is turned on. 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 open-connection on pin 25.
