(b) about the input selector short short mode is the command which makes switch s sh =on of input selector part so that the input impedance r in of all terminals becomes small. switch s sh is off when short command is not selected. the constant time brought about by the small resistance i nside and the capacitor outside the lsi becomes small when this command is used. the charge time of the capa citor becomes short. since short mode turns on the switch of s sh and makes it low impedance, please use it at no signal cond ition. 14. about mute terminal(pin 11) when power supply is off there should be no applied voltage across the mute terminal (pin 11) when power-supply is off. a resistor (about 2.2k) should be connected in series to mute terminal in case a voltage is supplied to mute terminal. (please refer application circuit diagram.) 15. about test pin test pin, should be open. pin 12 are test pins. n n p + p n n p + p substrate gnd n p + n n p + n p p substrate gnd gnd parasitic elements pin a pin a pin b pin b b c e parasitic elements gnd parasitic elements c be transistor (npn) resistor n region close-by parasitic elements 0 a(f) g db f hz c f r in ? input s sh ? ? ? ? ? ? 2 in 2 in fcr 2 1 fcr 2 fa ? ? ? ? downloaded from: http:///
