TDA2030 is a low frequency class AB amplifier provided by Dinghao Electronics, with a supply voltage of ±18V, an output power of 14W, high output current and very low harmonic and crossover distortion.
The TDA2030 is a monolithic integrated circuit in a Pentawatt® package, designed as a low‑frequency class‑AB audio amplifier capable of delivering up to 14 W into a 4 Ω load. It features high output current, low harmonic distortion, and built‑in short‑circuit and thermal shutdown protection.
The document includes absolute maximum ratings, electrical characteristics, thermal data, pin‑out diagrams, practical layout recommendations, and example application circuits for both split‑ and single‑supply configurations. Mechanical dimensions of the package are also provided.
