UTC TDA2050 是具有高功率能力的单片集成电路,旨在用作 AB 类音频放大器。

它可以在 VS=22.5V、f = 1KHz 的情况下,在 1 秒内向 4R 负载提供典型的 50W 音乐功率。

由于其高电源电压和极低的谐波和交叉失真,该设备最适用于 Hi-Fi 和高级电视机。

The UTC TDA2050 is a monolithic integrated circuit with high power capability and is designed to use as an class AB audio amplifier.

It can deliver typically 50W music power into 4R load over 1 sec at VS=22.5V, f = 1KHz.

The device is most suitable for both Hi-Fi and high class TV sets on the strength of its high supply voltage and very low harmonic and crossover distortion.
