S1T2418G01, TONE RINGER

TONE RINGER WITH DRIDGE DIODE S1T2418G01/D02 INTRODUCTION 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 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.
