HAA9809 Description:
HAA9809 Adaptive charge pump boost Adaptive charge pump boost,4 kinds of anti-crack optional, Class AB/Class D switching,5.4W mono audio power amplifier
The HAA9809 is a capacitive boost, crack-proof, Class AB/D switchable mono audio power amplifier that provides up to 5.4W continuous output power for 4Ω loads.
HAA9809 built-in unique anti-crack function, can automatically adjust the power amplifier gain according to the size of the output signal, prevent the output clipping distortion, to achieve a more comfortable hearing experience, HAA9809 also has a dynamic boost function, when the input signal is very small charge pump does not boost the voltage, for the through mode to reduce power consumption and improve efficiency; Charge pump boost is started when the input signal is large and a larger dynamic range is needed to achieve a perfect balance between efficiency and output power.
HAA9809's unique single-ended input architecture and extremely high PSRR effectively improve the HAA9809's ability to suppress RF noise. The HAA9809 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.
