Summary

SC1119 is a high fidelity, ultra-low EM, internal integration 32

Mono Channel Immunity with Scale Digital Volume Control and Top Cutting Distortion Prevention Function

Filtered class D audio power amplifier. In 5V power supply, 10% THD + N,

Under 4_load condition, output 36W high power, in all kinds of audio terminals

Maintain high efficiency in application and provide class AB amplifier with high fidelity and low noise

Acoustic performance.

AROC radiation and conduction interference suppression circuit makes SC1119 have

Excellent full bandwidth low radiation performance, without auxiliary filter design, transmission

The radiation level when the length of the horn line is 20 cm is much higher than that of the FCC Part 15.

Under Class B standard.

The anti-top distortion function of sc1119 can detect and suppress due to sound

Output Caused by Excessive Amplitude of Music and Speech Signal or Decline of Battery Voltage

Top-cutting distortion (broken sound), significantly improve the quality of sound, create a comfortable listening

Enjoy and protect speakers from overload damage. According to different needs

The anti-cutting roof has two modes of ACF-1 and ACF-2, which correspond to about 3% respectively.

And 10% maximum THD + N, while the chip has ACFO'mode.Sc1119 output without filter network, very few external component

It saves system space and cost and is an ideal choice for portable applications.In addition, the built-in shutdown function of SC111 minimizes standby current

It also integrates over-current protection, over-temperature protection and under-voltage abnormal protection.

Function.
