KA2418B/28  
TONE RINGER WITH BRIDGE DIODE  
INTRODUCTION  
8-DIP-300  
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
