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 (buzz-  
er)or a dynamic loudspeaker.  
SO8  
The output current capability of LS1240A is higher  
than standard ringer. For driving a dynamic loud-  
speaker LS1240A can simply use a decoupling ca-  
pacitor, thus eliminating the usual transformer.  
ORDERING NUMBERS  
No current limitation is provided on the output stage  
of LS1240A, so a minimum load DC of 50 is ad-  
viced, in series with a proper capacitor.

LS1240A  
LS1240AD1  
The two tone frequencies generated are switched  
by an internal oscillator in a fastsequence and made  
audible across an output amplifier in the loud-  
speaker, both tone frequencies and the switching  
frequency can be externally adjusted.  
The supply voltage is obtained from the AC ring sig-  
nal and the circuit is designed so that noise on the  
line or variations of the ringing signal cannot affect  
correct operation of the device.
