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 components. * Integrated voltage and current hysteresis.  ORDERING INFORMATION Ordering Number Lead Free Halogen Free LS1240AL-D08-T LS1240AG-D08-T LS1240AG-S08-R  Package Packing DIP-8 SOP-8 Tube Tape Reel MARKING DIP-8 www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd SOP-8 1 of 5 QW-R108-002.J PDF
