TONE RINGER WITH BRIDGE DIODE

INTRODUCTION

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 is obtained from

the AC ring signal and the circuit is designed so that noise on the

line or variation of the ringing signal can not affect correct operation

of the device.

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 voltage to

current hysteresis

Adjustable activation voltage

Internal zener diodes to protect against over

voltages

Adjustable ringer impedance with external

components.
