Working principles:
of TDA2003 Amplifier Single Supply
The TDA2003 power amplifier operates by amplifying the input signal and driving a load, such as a speaker or headphones. The input signal is first passed through a pre-amplifier stage, which amplifies the signal to a level that can be handled by the TDA2003 power amplifier. The TDA2003 power amplifier then amplifies the signal further and delivers it to the load connected to its output pins.
The TDA2003 power amplifier has two inputs: one for the audio signal and the other for the ground. The input signal is an AC voltage, which is coupled to the base of an NPN transistor. The transistor amplifies the signal and drives a second NPN transistor in push-pull mode. The push-pull configuration amplifies the signal further and provides a higher power output.
