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 pleasi.
• 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.
