LINEAR INTEGRATED CIRCUIT

ELECTRONIC TONE RINGER

WITH BUILT-IN BRIDGE

RECTIFIER

DESCRIPTION

The UTC LS1240A is monolithic integrated circuits and

designed to be as a telephone ringer. It can drive a piezo-ceramic

converter(buzzer) directly. The output current capacity of UTC

LS1240A is higher than standard ringer. For driving a dynamic

loudspeaker, UTC LS1240A needs only a decoupling capacitor to

replace the usual transformer in use.

FEATURES

* Low current consumption.

* Integrated rectifier bridge with zener diodes to overvoltage

Protection.

* Minimum external circuitry.

* Both frequencies of tone and switching are adjustable by external

components.

* Integrated voltage and current hysteresis.
