FUNCTIONAL DESCRIPTION
The TDA7052 is a mono output amplifier designed for battery-fed portable audio applications, such as tape recorders
and radios.
The gain is fixed internally at 40 dB. A large number of tape recorders and radios are still designed for mono sound, plus
a space-saving trend by reduction of the number of battery cells. This means a decrease in supply voltage which results
in an reduction of output power. To compensate for this reduction, the TDA7052 uses the Bridge-Tied-Load principle
(BTL) which can deliver an output power of 1,2 W (THD = 10%) into an 8
can be short-circuited at each signal excursion.
