1 / 5 page UNISONIC TECHNOLOGIES CO., LTD LS1240A LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 5 Copyright © 2012 Unisonic Technologies Co., Ltd QW-R108-002.I 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.
