CST8302A

    CST8302A is a 6.23W monaural audio power amplifier with FM interference free, four anti distortion AB/D switchable, high efficiency, and no filters. The ultra-low EMI is very suitable for use in portable devices with FM function.

CST8302A Summary:
    CST8302A is a 6.23W monaural audio power amplifier with FM interference free, four anti distortion AB/D switchable, high efficiency, and no filters. The ultra-low EMI is very suitable for use in portable devices with FM function.
    The differential input architecture and extremely high PSRR of CST8302A effectively improve its ability to suppress RF noise. The PWM modulation structure without the need for filters and the built-in gain method reduce external components, PCB area, and system costs, and simplify the design. With an efficiency of up to 91%, fast startup time, and slim package size, CST8302A is the best choice for portable audio products.
   CST8302A has an extremely low turn off current, greatly extending the standby time of the system. The OCP, OTP, and UVLO protection functions enhance the reliability of the system. Enabling and disabling the POP pack suppression function improves the auditory experience of the system and simplifies system debugging.
    CST8302A has a one line pulse function that only requires the use of one IO port. It can control the power amplifier to turn on and off, switch between D-class anti sound mode, D-class normal mode, and AB class mode at will, achieving the goal of saving IO ports for users. If the one line pulse function is not used, the EN pin can also be controlled separately to easily switch to various working modes. In AB class mode, it can solve the interference problem of traditional D-class power amplifiers on FM and completely eliminate EMI interference.
    CST8302A offers ESOP8 package with heat sink.
