HAA2820 Description:
The HAA2820 is a capacitive boost, crack-proof, Class AB/D switchable mono audio power amplifier that provides up to 5W continuous output power for 4Ω loads.
HAA2820 built-in unique anti-crack function, can automatically adjust the power amplifier gain according to the size of the output signal, to prevent the output clipping distortion, to achieve a more comfortable hearing experience, HAA2820 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.
HAA2820's fully differential input architecture and extremely high PSRR effectively improve HAA2820's ability to suppress RF noise.
The HAA2820 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 HAA2820 is available in an eTSSOP16 package with heat sink
