KA2418B

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.
