The HAA9806 is a built-in BOOST module with anti-crack-proof, Class AB/D switchable mono audio power amplifier that provides up to 10W continuous output power for 2Ω loads.
    HAA9806 built-in unique anti-crack function, can automatically adjust the amplifier gain according to the size of the output signal, prevent the output cutting distortion, to achieve a more comfortable hearing experience.
    The HAA9806's fully differential input architecture and extremely high PSRR effectively improve the HAA9806's ability to suppress RF noise.
The HAA9806 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 HAA9806 is available in an ESOP8 package with heat sink
