SC2118

      SC2118 is a stereo Class D audio power amplifier with ultra-low EMI and anti-breaking distortion. It can output up to 3.6W under the condition of 5V power supply, THD + N = 10%, 4Ω load. Power, while providing performance comparable to Class AB amplifiers, the efficiency is as high as 90%. The biggest feature of SC2118 is the anti-breaking distortion (NCN) output control function, which can detect and suppress the output signal clipping distortion (breaking sound) caused by the input music and the excessive amplitude of the voice signal. It can also adaptively prevent the The output shaving caused by the drop of the power supply voltage in the application significantly improves the sound quality, creates a very comfortable music enjoyment, and protects the speakers from overload damage. By connecting different resistor and capacitor values to the ACRC terminal, the sound quality and output power of the amplifier can be flexibly set; at the same time, the chip provides NCNOff mode.

     SC2118 adopts unique electromagnetic radiation (EMI) suppression technology, which has super excellent full bandwidth and low radiation performance. The radiation level is still far lower than FCC Part15 Class B standard without any auxiliary design.

     SC2118 integrates filter-free digital modulation technology, which can directly drive the speaker and minimize the distortion and noise of the pulse output signal. Very few external components save system space and cost, making it ideal for portable applications.
