KA2428 Description

KA2418B/28 INTRODUCTION TONE RINGER WITH BRIDGE DIODE The KA2418B/28 is a monolithic integrated circuit telephone tone ringer with bridge diode, when coupled with an appropriate transducer, it replaces the electromechanical 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 a high frequencys (fH1, fH2) alternating...
