FUNCTIONAL DESCRIPTION
TEA7530performs the following functions:
The circuit amplifies the incoming signal and
feeds it to the loudspeaker.
The Antidistortion system is incorporated for
low current available from line.
The maximum power available on a 50
im-
pedanceloudspeaker is 25mW at 3V and 100mW
at 5V.
