The TDA2030A is an audio integrated power amplifier developed by SGS of Italy. It is packaged in a 5-pin plastic package with short-circuit and over-temperature protection inside the circuit. The typical application circuit is shown in the figure above. The technical parameters of the TDA2030A are shown in Table 5-2.
TDA2030A is actually a modified version of TDA2030. The former can replace the latter. The main difference between the two is that the highest voltage and voltage VM are different from the output power PO. If the TDA2030 is used instead of the TDA2030A, the power supply voltage and audio output of the whole machine must be seen. power. When the VCC voltage of the TDA2030A is positive or negative 16V, and the output audio power is not more than 9W (RL=8 ohms) or 4W (RL=4 ohms), it is not a problem to replace the TDA2030A with the TDA2030. On the contrary, after the replacement, the TDA2030 or the audio output power is easily damaged to the level of the original machine.
