IL2418 - Two-Tone Telephone Ringer

The IL2418 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 tone

TECHNICAL DATA Telephone Tone Ringer with Bridge Diode The IL2418 is a monolithic integrated circuit telephone tone ringer with bridge diode, when coupled with an appropriate transducer, it replaces the electro-mechanical bell.

The device is designed for use with either a piezo transducer or an inexpensive transformer coupled speaker to produce a pleasing tone composed of a high frequency (fR) alternating with a low frequency (fL) resulting in a warble frequency.

The supply voltage is obtained
