Summary

SC2308 is a wide supply voltage range (3~8.5V)

Class D audio power amplifier, the maximum supply voltage can reach 8.5V VDD = 8.5V THD + N = 10%, 4 load, can output 10W continuously.

Power.

SC2308 has anti-breaking noise distortion (NCN) output control function. It can detect and suppress the top-cutting distortion (breaking) of output signal caused by the excessive amplitude of input music and speech signal, and significantly improve the quality of sound

Build comfortable listening enjoyment and protect loudspeaker from overload damage. At the same time, the chip also has NCN-Off mode configurable.

SC2308 integrates filter-free digital modulation technology, which can directly drive the loudspeaker and minimize the distortion and noise of the pulse output signal. The output does not need a filter network, and very few external components save system space and cost. It is an ideal choice for portable applications.

In addition, the built-in shutdown function of SC2308 minimizes the standby current, and integrates the functions of output overcurrent protection, on-chip overtemperature protection and power supply under-voltage abnormal protection.
