LS1240A
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.
LINEAR INTEGRATED CIRCUIT
SOP-8
DIP-8
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.
*Pb-free plating product number: LS1240AL
