CST8102A Summary:
CST8102A is a high-efficiency, unfiltered 5.2W mono AB/D class audio amplifier. The ultra-low EMI is very suitable for application in portable devices with FM function.
The single ended input architecture and extremely high PSRR of CST8102A 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 CST8102A the best choice for portable audio products.
CST8102A has a disconnect function that greatly extends the standby time of the system. The overheat protection function enhances the reliability of the system. The POP sound suppression function improves the auditory perception of the system and simplifies system debugging.
CST8102A provides ESOP8 packaging with heat sinks.
