Product Highlights
1.The VC8210 is an FM-interference-free, anti-clipping, switchable AB/D class, high-efficiency, filterless 3.1W mono audio power amplifier. Its ultra-small package makes it ideal for wearable devices.

2.The VC8210's differential input architecture and extremely high PSRR effectively improve its RF noise suppression. The filterless PWM modulation structure and built-in gain reduce external components, PCB area, and system cost, simplifying design. Up to 90% efficiency, fast startup time, and a small package size make the VC8210 an optimal choice for portable audio products.

3.The VC8210 features extremely low shutdown current, significantly extending system standby time. OCP, OTP, and UVLO protection enhance system reliability. On/off pop-click suppression improves the listening experience and simplifies system setup.

4.The VC8210 is available in a heatsinked DFN2X2_8L package.
