30W Bridge Amplifier Circuit

TDA2040
20W Hi-Fi AUDIO POWER AMPLIFIER
DESCRIPTION
The TDA2040 is a monolithic integrated circuit in
Pentawatt[ package,intended for use as an audio
class AB amplifier. Typically it provides22W output
power (d = 0.5%) at Vs = 32V/4W . The TDA2040
provides high output current and has very low
harmonic and cross-over distortion. Further the
device incorporates a patented short circuit protection
system comprising an arrangement for automaticallylimiting
the dissipatedpowersoas to keep
the working point of the output transistors within
their safe operating area. A thermal shut-down
system is also included.
