LS1240A規(guī)格書詳情

DESCRIPTION

LS1240A 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 LS1240A is higher than standard ringer. For driving a dynamic loudspeaker LS1240A can simply use a decoupling capacitor, thus eliminating the usual transformer. No current limitation is provided on the output stage of LS1240A, so a minimum load DC of 50 ? is adviced, in series with a proper capacitor.

■ LOW CURRENT CONSUMPTION, IN ORDER TO ALLOW THE PARALLEL OPERATION OF 4 DEVICES

■ INTEGRATED RECTIFIER BRIDGE WITH ZENER DIODES TO PROTECT AGAINST OVERVOLTAGES

■ LITTLE EXTERNAL CIRCUITRY

■ TONE AND SWITCHING FREQUENCIES ADJUSTABLE BY EXTERNAL COMPONENTS

■ INTEGRATED VOLTAGE AND CURRENT HYSTERESIS
