LS1240A規(guī)格書詳情
LS1240A屬于集成電路(IC)的電信。由意法半導(dǎo)體集團制造生產(chǎn)的LS1240A電信電信接口集成電路 (IC) 為通信網(wǎng)絡(luò)接口提供特定功能和控制,例如以太網(wǎng)切換、線路驅(qū)動器、ISDN、放大器、通道擴展器、數(shù)字鎖相環(huán)、DTMF、音頻發(fā)生器和解碼器、回聲消除、檢測器和發(fā)生器、DDA、電話線路監(jiān)控器和主叫號碼標(biāo)識。
Description
LS1240 is a monolithic integrated circuit designed to replace the mechanical bell in telephone sets in connection with an electro-acoustical converter. It can drive directly a piezoceramic converter (buzzer) or a dynamic loudspeaker.
The output current capability of LS1240 is higher than the one of a standard ringer. To drive a dynamic loudspeaker LS1240 can simply use a decoupling capacitor, thus eliminating the usual transformer.
No current limitation is provided on the output stage of LS1240, so a minimum load DC of 50 ? is advised, in series with a proper capacitor.
Features
■ Low current consumption, in order to allow the parallel operation of 4 devices
■ Integrated rectifier bridge with zener diodes to protect against over voltages little external circuitry
■ Tone and switching frequencies adjustable by external components
■ Integrated voltage and current hysteresis
