NOTE: Absolute maximum ratings are those values beyond which permanent damage to the device may occur. These are stress ratings only and functional operation of the device at or beyond them is not implied. Long exposure to these conditions may affect device reliability.


Description

The S1T2418G01/D02 is a monolithic integrated circuit telephone tone ringer with bridge diode. When coupled with an appropriate transducer, it replaces the electro-mechanical bell.

This S1T2418G01/D02 device is designed for use with either a piezo transducer or an inexpensive transformer-coupled speaker to produce a pleasing tone composed of high frequencies (fH1, fH2) alternating with a low frequency (fS) resulting in a warble frequency.

The S1T2418G01/D02 supply voltage is obtained from the AC ring signal and the circuit is designed so that noise on the line or variation of the ringing signal cannot affect correct operation of the device.
