ELECTRONIC TONE RINGER ?WITH BUILT-IN BRIDGE ?RECTIFIER

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 \nLS1240A is higher than standard ringer. For driving a dynamic loudspeaker, UTC LS1240A needs only a decoupling cap ? Low current consumption. \n? Integrated rectifier bridge with zener diodes to overvoltage Protection. \n? Minimum external circuitry. \n? Both frequencies of tone and switching are adjustable by external components. \n? Integrated voltage and current hysteresis.;
