Stereo audio amplifier with TDA 2004

The TDA2004A is a class B dual audio power amplifier (10 + 10W STEREO AMPLIFIER) in MULTIWATT package specifically designed for car radio applications.
stereo amplifiers are easily designed using this device that provides a high current capability (up to 3.5A) and that can drive very low impedance loads (down to 1.6 ohm).
Its main features are :
Low distortion, Low noise, High reliability of the chip and of the package with additional safety during operation.
space and cost saving : very low number of external components,very simple mounting system with no electrical isolation between the packageand the heatsink.
you can see the schematic circuit for amplifier aplication below:

with this circuit you can easily boost your audio level, from your stereo walkman, Ipod, tuner, MP3 or MP4 player, portable receiver, laptop or PC.
PIN connection of TDA 2004 is described in this picture:

The maximum operating DC voltage on the TDA2004A is 18 V.
However the device can withstand a DC voltage up to 28V with no damage.
this information above is based from datasheet TDA2004A issued by SGS-Thomson Microelectronics
