CST8302M Summary:
CST8302M is a 3.2W mono audio power amplifier with FM interference free, AB/D switchable anti burst sound, 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 CST8302M effectively improve its ability to suppress RF noise. The PWM modulation structure without filters and the built-in gain method reduce the external component PCB area and system cost, and simplify the design. Up to 90% efficiency, fast startup time, and small packaging size make the CST8302M the best choice for portable audio products.
CST8302M 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.
CST8302M provides MSOP8 packaging with heat sinks
