S1T2418D02 Description
TONE RINGER WITH DRIDGE DIODE 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 posed of high frequencies (fH1, fH2) alternating with a low...
