TDA2030是德律风根公司生产的功放集成块,它在音响电路中的使用已为广大爱好者所熟悉。然而TDA2030能否用于工业控制,却很少有人探讨。笔者认为该集成块具有使用电压范围广,频率特性好,输入阻抗高,输出电流大,外围元件少等特点,而且特别可贵的是它具有输出短路保护和过载热保护,因此,使用TDA2030能简化电路设计,对提高可靠性,降低成本具有明显的效果。
TDA2030 is the German Telefunken company’s amplifier block, it is used in audio circuits have been familiar to the majority of fans. However, TDA2030 can be used for industrial control, but few people explore. I believe that the integrated block has a wide range of use voltage, good frequency characteristics, high input impedance, large output current, less external components, etc., and particularly valuable is that it has output short circuit protection and thermal overload protection, therefore, the use of TDA2030 can be simplified Circuit design, to improve reliability and reduce costs with obvious results.
