The HAA9105 is a Class D audio power amplifier with high efficiency and no output filter mono 5.3W.
    The HAA9105's unique single-ended input architecture and extremely high PSRR effectively improve the HAA9105's ability to suppress RF noise. The filter-free PWM modulation structure and gain built-in approach reduce external components, PCB area and system costs, and simplify design. Up to 90% efficiency, fast start-up time and small package size make the HAA9105 the perfect choice for portable audio products.
    The HAA9105 has a very low turn-off current, greatly extending the standby time of the system. The OCP, OTP, and UVLO protection functions enhance system reliability. Turning POP-click suppression on and off improves the auditory perception of the system and simplifies system debugging.
     The HAA9105 is available in an ESOP8 package with heat sink
