The AXS2033 is an FM interference free, Class AB/D switchable, high-efficiency, filter-free 3.1W mono audio power amplifier. The ultra-small package is ideal for use in wearable products.
    The AXS2033's differential input architecture and extremely high PSRR effectively improve the AXS2033'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 AXS2033 the perfect choice for portable audio products.
    The AXS2033 has an extremely 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 AXS2033 is available in a DFN2X2_8L package with heat sink.
