CIRCUIT DESCRIPTION
TEA7530 is a 8 pin DIP integrated circuit provid-
ing the followingfacilities:
Loudspeakeramplifier
Antidistortion feed-back system (limited line
current compensation)
1.1. LOUDSPEAKERAMPLIFIER
The amplifier is divided into 2 mainsections.
- AutomaticGain Control (AGC)
- Push-pull amplifier (bridge structure)
a) The AGC section is used for the antidistortion
system.
When used in a telephone set to avoid larsen
effect the AGC automatically decreases loud-
speaker amplifier gain.
When the required output level exceeds the
capabilities of the available current, the AGC
decreases the loudspeaker amplifier gain to
avoids distortion.
b) The output amplifier uses a double push-pull
configuration(H bridge) to get maximum dynamic
rangeunder limited supply conditions.
