(please refer application circuit diagram.) 5. about signal input terminals because the inner impedance of the terminal becomes 100 k or 250 k when the signal input terminal makes a terminal open, the plunge noise from outside sometimes becomes a problem. when there is a signal input terminal not to use, design so as not to ground. 6. about changing gain of input gain and fader volume in case of the boost of the input gain and fader volume when changing to the high gain which exceeds 20 db especially, the switching shock noise sometimes becomes big. in this case, we recommend changing every 1 db step without changing a gain at once. also, the shock noise sometimes can reduce by making advanced switch time long, too. 7. about inter-pin short to vcch vcch terminal(21pin) is assumed that applied high voltage(17.8v max ) for realization of 5.2vrms(max) output. and so, avoid short between vcch and scl, other. when inter-pin shorts, circuit current increase rapidly, and it may result in property degradation and destruction of a device.
