ELETRONIC TWO-TONE RINGER

DESCRIPTION L3240 is a monolithic integrated circuit designed to replace the mechanical bell in telephone sets, in connection with an electro acoustical converter.The device can drive either directly a piezo ceramic converter (buzzer) or a small loudspeaker. In this case a transformer is needed
