NS4215 Description:
The NS4215 is an ultra-low EMI, filter free Class D stereo audio power amplifier capable of delivering 7.5W per channel.
The NS4215 uses advanced technology to greatly reduce EMI interference over the full bandwidth range, minimizing the impact on other components. Its output filter-free PWM modulation structure reduces external components, PCB area, and system costs. The unique anti-distortion (NCN) function can effectively prevent output signal distortion caused by input signal overload, and achieve a more comfortable hearing experience. At the same time, it can effectively protect the speaker from being damaged when the high power output.
NS4215 built-in overcurrent protection, overheat protection and undervoltage protection functions, effectively protect the chip from being damaged under abnormal working conditions.
The NS4215 is available in the TSSOP-24 package and is rated for operating temperature ranges from -40 ° C to 85 ° C.
