HAA9206B Overview:
HAA9206B is a low EMI, single channel Class D audio power amplifier with four anti burst functions.
The single ended input architecture and extremely high PSRR of HAA9206B effectively improve its ability to suppress RF noise. The PWM modulation structure and gain built-in method without filters reduce external components, PCB area, and system costs, and simplify design. Up to 90% efficiency, fast startup time, and small packaging size make the HAA9206B the best choice for portable audio products.
HAA9206B has extremely low shutdown current, greatly extending the standby time of the system. The OCP, OTP, and UVLO protection functions enhance the reliability of the system. Turning on and off the POP-click suppression function improves the auditory perception of the system while simplifying system debugging.
HAA9206B offers ESOP8 packaging with heat dissipation fins.
