■ 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.
