General Description
GL6840A are monolithic integrated circuits 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.
