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.

LS1240A 線性集成電路
內置橋式整流器的電子鈴聲

描述

UTC LS1240A 是單片集成電路,設計用作電話振鈴器。 可直接驅動壓電陶瓷轉換器(蜂鳴器)。 UTC LS1240A的輸出電流容量高於標準振鈴器。 為了驅動動態揚聲器,UTC LS1240A 只需要一個去耦電容來代替常用的變壓器。

特徵
  • 低電流消耗。
  • 帶有齊納二極管的集成整流橋可提供過壓保護。
  • 最小的外部電路。
  • 音調頻率和開關頻率均可通過外部元件進行調節。
  • 集成電壓和電流遲滯。
