This makes it robust to be used in automotive audio designs such as car stereos. It has an operating voltage of 18V but can handle high voltages up to 28V. It can also handle short circuits in both AC & DC rails without damaging itself. This amplifier IC can output up to 3.5A current to drive speakers & can also handle high currents up to 5A for a shorter duration without any damage. TDA2003 is a general-purpose audio amplifier circuit IC for stereo or mono audio design circuits. we will design a 7 Watt audio amplifier circuit using a TDA2003 audio amplifier IC. Different kinds of sound systems such as sound reinforcement systems, public addresses, home audio systems & musical instrument amplifiers like guitar amplifiers use different types of audio amplifiers. An audio power amplifier is an electronic amplifier that amplifies low-power audio signals such as the signal from a radio receiver or an electric guitar to a level that is strong enough for driving loudspeakers or headphones.
