LS1240A
ELECTRONIC TONE RINGER
WITH BUILT-IN BRIDGE
RECTIFIER
LINEAR INTEGRATED CIRCUIT
„ 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.
