Overview

UNISONIC TECHNOLOGIES CO.
, LTD LS1240A 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 compon...
