IL6840A

Telephone Tone Ringer

IK Semiconductor

IL6840A General Description

The IL6840A tone ringer derives its power supply by rectifying the AC ringing signal. It uses this power to activate two tone generators. The two tone frequencies generated are switched by internal oscillator in a fast sequence and made audible across an output amplifier in the loudspeaker; both ton.
