Descriptiondescribe
HM8875 is a high-efficiency, filter-less monophonic Class F audio power amplifier with built-in boost function and anti-crack function.
The differential input architecture of HM8875 effectively improves the immunity to RF noise. The anti-crack function solves the problem of inconsistent output amplitudes of different sound sources, and at the same time brings perfect music enjoyment without distortion. The PWM modulation structure without filter and the built-in gain method reduce external components, PCB area and system cost, and simplify the design. The fast startup time and small package size make the HM8875 an excellent choice for Bluetooth speakers and other portable audio products.
