NS4150
NS4150 (stop production) (stop production)
The NS4150 is an ultra-low EMI, filter-free 3W mono Class D audio power amplifier. The NS4150 uses advanced technology to greatly reduce EMI interference over the full bandwidth range, minimizing the impact on other components.
NS4150 built-in overcurrent protection, overheat protection and undervoltage protection functions, effectively protect the chip from being damaged under abnormal working conditions. The new circuit design is fully optimized using spread spectrum technology, and the efficiency of up to 90% is more suitable for portable audio products.
