CST8302 Overview:
CST8302 is a 5.2W mono audio power amplifier with FM interference free, AB/D switchable sound protection, high efficiency, and no filter. The ultra-low EMI is very suitable for application in portable devices with FM function.
The differential input architecture and extremely high PSRR of CST8302 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 the design. Up to 90% efficiency, fast startup time, and small packaging size make CST8302 the best choice for portable audio products.
CST8302 has an extremely low turn off current, greatly extending the standby time of the system. The reliability of the system is enhanced by OCP, OTP, and UVLO protection functions. Enabling and disabling the POP click suppression function improves the auditory perception of the system while simplifying system debugging.
CST8302 provides ESOP8 package with heat sink
