The TDA2030A is a 18W Hi-Fi amplifier and 35W driver, suitable for low frequency class AB amplifier. It provides high output current and very low harmonic and cross-over distortion. It also has a short circuit protection system, which includes an arrangement for automatically limiting the dissipated power so as to keep the working point of the output transistors within their safe operating area. A conventional thermal shut-down system is also included.
The TDA2030A is a monolithic audio power amplifier IC in a Pentawatt package, designed for low‑frequency class‑AB operation with a maximum supply voltage of 44 V. It offers high output current, low harmonic distortion, and built‑in short‑circuit and thermal shutdown protection, making it suitable for reliable 18 W Hi‑Fi and 35 W driver applications.
