Summary

Sc1106 is a low EM, anti-crown distortion, mono

Class D audio power amplifier without channel filter. At 5V power supply, 10%

Under THD + N, 4Q load, output 36 power (WLCSP9)

Encapsulation, maintains high efficiency in various audio terminal applications and provides AB

Performance of class A amplifier.

The biggest characteristic of sC1106 is the output of anti-cutting top distortion (ACF).

The control function can detect and suppress the input music and speech signal amplitude.

The output signal distortion caused by overshooting can also be self-contained.

Adaptively prevent power supply voltage drop in battery applications

Cutting the top of the output can significantly improve the sound quality and create a very comfortable listening enjoyment.

It also protects the loudspeaker from damage caused by overload. For different application needs, prevent

Top-cutting has two modes of ACF-1 and ACF2, which correspond to about 3% respectively.

And 10% maximum THD + N, while the chip has ACFO mode

SC1106 has a unique electromagnetic radiation (EM) suppression technology

And excellent full-bandwidth low radiation performance, radiation level without any supplement

Help design is still far below FCC Pal15 Class B standard, no

It avoids interfering with other sensitive circuits and reduces the difficulty of system design.

SC1106 integrates filter-free digital modulation technology to enable

Direct drive loudspeaker and minimize the loss of pulse output signal

True and noisy. Output without filter network, very few external components

It saves system space and cost and is an ideal choice for portable applications.

In addition, the built-in shutdown function of SC1106 minimizes standby current

It also integrates output over-current protection, on-chip over-temperature protection and power supply.

Undervoltage abnormal protection and other functions.
