This 10W audio amplifier circuit is designed using TDA2003 audio amplifier IC which is a simple and low power audio amplifier, that require few electronic components .
This 10W audio amplifier circuit can provide an approximate 10 Watts power for a 2 ohms load and 4 watts for 4 ohms load. The maximum power can be obtain with a 16 V Dc power supply and a current above 1 ampers for a 2 ohms impedance speaker . A power above 4 watts can be obtain with a 12 volts DC power supply and a current above 1 amper for 4 ohms impedance .
The TDA2003 has improved performance with the same pin configuration as the TDA2002.
The TDA2003 device provides a high output current capability (up to 3.5A) very low harmonic and cross-over distortion. Completely safe operation is guaranteed due to protection against DC and AC short circuit between all pins and ground, thermal over-range, load dump voltage surge up to 40V and fortuitous open ground.
