HAA9203B
HAA9203B is an FM interference free, anti-break AB/D class switchable, high efficiency, no filter 5.3W mono audio power amplifier; Ultra-low EMI is ideal for use in portable devices with FM capabilities.
HAA9203B's differential input architecture and extremely high PSRR effectively improve the ability of HAA9203B to suppress RF noise. The filter-free PWM modulation structure and gain built-in method reduce external components, PCB area and system cost, and simplify design; Up to 90% efficiency, fast start-up time and small package size make the HAA9203B the best choice for portable audio products.
