Product Summary
The AN7348K is a dual record/playback pre-amplifier IC for double cassette. It is a monolithic integrated circuit designed for double cassette recorder . It has dual channel PB/Recamplifier with ALC function. Tape A(PB only)and Tape B(PB/Rec select, Normal/Chrome select,Normal/High speed dubbing select and Rec/PB selection are easily controlled by 4 pins. It requires no external FET switches at PB amp.input and Rec amp.output. External components are also minimized.In addition,this Ic has low susceptibility to EMC.
