DESCRIPTION  
ORDERING NUMBER: TEA7533FP  
This 20 pins IC is designed for monitoring and  
loudspeaker telephone set and provides:  
a) signal amplification for monitoring (loudspeaker).  
b) antiacoustic feedback (antilarsen).  
c) antidistortion by automatic level adaptation.  
d) antilarsen adjustment (full duplex).  
e) antidistortion by automatic gain adaptation in  
current supply mode.  
feeds it to the loudspeaker. PG0, PG1 and PG2  
inputs are used to set the loudspeaker gain in a  
range of 32dB to 5dB in 7 steps of 4.5dB.  
The TEA7533 inputs (PG0, PG1, PG2) allows  
also the loudspeaker to be cut-off, thus ensuring  
privacy of communication.  
f) service audio inputs with internal dedicated  
switches.  
The antilarsen (antiacoustic feedback) system  
is incorporated.  
FUNCTIONAL DESCRIPTION  
The maximum power available on a 50im-  
pedance loudspeaker is 140mW at 5V and  
250mW at 6.5V.  
TEA7533 performs the following functions:  
The circuit amplifies the incoming signal and
