Working Principle

BH7826FVM-TR is a Class-D linear audio amplifier. It converts the electrical signal into an instensity-modulated pulse train formed of a series of discrete pulses, each of which is at perfect switching levels. The pulses are amplified by the power transistors and saturate the output inductor. The leakage inductance of the output inductor combines with the capacitance of the output capacitor and linearly converts the pulse train of the amplifier into a continuous and filterable output. The filtered output signal, which has been amplified, is then fed to the load.

BH7826FVM-TR also has embedded protections such as over-voltage protection, under-voltage protection, short-circuit protection, thermal protection, and over-temperature protection which prevent the amplifier from shorting and damaging the equipment due to external power supplies or other challenges.

Conclusion

BH7826FVM-TR linear audio amplifier is a reliable and high performance device designed for sound processing, commercial audio, and car audio applications. Its wide input voltage range and high power output make it suitable for a variety of audio devices and speakers. Its class-D design allows it to convert the electrical signal and produce a filtered, amplified output. Furthermore, its built-in safety protections offer robust protection and preserve the functionality of the amplifier.
