KA2418B TONE RINGER WITH BRIDGE DIODE

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 composed of a high frequencys (fH1, fH2) alternating with a low frequency (fS) resulting in a warble frequency. The supply voltage i.

KA2418B Features

* Built-in full wave bridge diode rectifier

* Low current consumption, in order to allow the parallel operation of the 4 devices

* Few external components

* Tone and adjustable switching frequencies by external components

* High noise immunity due to built-in
