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. The two tone frequencies generated are switched by an internal oscillator in a fast sequence and made audible across output amplifiers in the transducer, both tone frequencies and switching frequency can be externally adjusted.
Features
? Low current consumption, in order to allow the parallel operation of 4 devices
? Integrated rectifier bridge with zener diodes to protect against overvoltages
? Little external circuitry
? Tone and switching frequencies adjustable by external components
? Integrated voltage and current hysteresis
? Bridge output configuration
