The uA758 is a monolithic phase-locked loop FM stereo multiplex decoder. The device decodes an FM stereo multiplex signal into right and left audio channels while inherently suppressing SCA information when it is contained in the composite input signal. The device includes automatic mono-stereo mode switching and a drive for an external lamp to indicate stereo mode operation. The uA758 operates over a large voltage range and requires a minimum number of external components. A simple setting of an external potentiometer adjusts the oscillator frequency. No coils are required.
