Description
NS4358 is an ultra-low EMI, filter-free, 5W+3W×2 high-efficiency 2.1-channel Class D audio amplifier. The NS4358 uses advanced technology to greatly reduce EMI interference across the full bandwidth, minimizing the impact on other components. Its output PWM modulation structure without filter and built-in feedback resistor reduce external components. It integrates the 2.1 channel function and band-pass filter on a single chip, requiring only a few peripheral components and maximally saving PCB. area and system cost.
Main Features
