Description: 10W CAR RADIO AUDIO AMPLIFIER. Manufacturer: STMicroelectronics.

2019年7月5日 · TDA2003 is a general-purpose 10W amplifier IC that can be used in stereo or mono audio design circuits. The amplifier can output upto 3.5A current to drive speakers and can also handle high current upto 5A for shorter duration without any damage. It can also handle short circuits in both AC and DC rail without killing itself.

The TDA2003A is capable of providing a high output current (up to 3.5 A) with very low harmonic and crossover distortion.

6 天之前 · See, this is a TDA2003 amplifier circuit, a popular IC from SGS Thomson. Why we should use this? It is the normal operation of the integrated circuit, the music amplifier for car audio radio sound. Which uses a supply voltage from a 12V car battery. But this circuit is adapted for use in a home. By changing the power supply voltage to 18V.

The TDA 2003 has a circuit which enables it to withstand a voltage pulse train, on pin 5, of the type shown in fig. 19.

2017年9月28日 · Here is the circuit diagram of a 10W audio amplifier using the popular TDA2003 IC from SGS Thomson. The IC can easily deliver 10W to a 4 Ohms load at 18V DC supply voltage. The IC can be also operated from 12V and that makes it applicable in car audio systems.

The TDA2003A is capable of providing a high output current (up to 3.5 A) with very low harmonic and crossover distortion.

TDA2003的ic在多媒体中可以说是用得最普遍的一款ic了，功率不大，而且 失真度 也很小，才0.5%。 所有的接地的都要接回到负极也即是哪一个负极导线，输入端相当于正极，一正一负，就构成了回路。 这个图只是一个原理图，画好PCB图你就明白了。 TDA2003 后级功放 应该没问题，问题出在前级或 分频频率 定得太低。 先将信号线的地，接到 功放 输入的地端；信号线的另一端，串接一电容（如474n），信号源的信号别开太大，从后级顺往前级，一级一级接查，那个 …
