Several kinds of high power amplifier integrated blocks are introduced.

Some high-power power amplifier integrated blocks are as follows:

1 and LM3886 are a new type of 68W mono high-fidelity power amplifier with over-voltage and over-temperature protection and mute function.

2.TDA7294 A new high-power DMOS power amplifier chip TDA7294 introduced by stmicroelectronics is very popular among audio lovers because of its high power, perfect protection function and good timbre.

3.IM 1875 is a power amplifier integrated block developed by American semiconductor company. The integrated circuit has built-in overload and overheating and inductive load back emf safety protection.

4.TDA7294 is a class AB monolithic audio power amplifier integrated circuit introduced by stmicroelectronics Company in 1990s. It sweeps away the cold and stiff timbre of the previously successfully released linear integrated power amplifier and thick film sleeve, and is widely used in HiFi fields such as home theater, active speakers and high-performance TV.

5.TDA2030A is an audio power amplifier circuit produced by Telephon Company, which adopts V-shaped 5-pin single-wire straight-in plastic package structure.
