TDA2030A is a monolithic audio power amplifier integrated circuit produced by Contek company. It has the advantages of low external components, high current output, high operating voltage, low distortion, etc.
This document describes the Contek TDA2030A linear integrated circuit, a monolithic audio power amplifier IC designed for hi‑fi applications. It includes a brief description, key features such as low external component count, high current output, built‑in over‑temperature and short‑circuit protection, and the TO‑220B package pinout.
Detailed electrical characteristics, test conditions, typical performance graphs, and example application circuits are presented. Protection mechanisms, thermal shutdown behavior, and component recommendation tables help designers implement the device in both single‑supply and split‑supply configurations.
