The TDA2030 amplifier circuit is a monolithic IC intended for use as a low frequency class AB amplifier. TDA2030 provides 14W output power (distorsions = 0.5%) at 14V/4Ω and at ± 14V or 28V is 12W/4Ω or 8W/8Ω. TheTDA2030 provides high output current and has very low harmonic and cross-over distortion which made it one of the most used IC in audio amplifiers designs.
TDA2030 can be connected in several ways to deliver different power ratings and characteristics, so we start with the simplest circuit design.
