LS1240A规格书详情
描述 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.
特性 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.
