Characteristic

The patented EDMA technology which reduces internal resistance and heat consumption greatly improves output power and product reliability Po=3.6 W (VDD=5.0V, RL=4, THD+N=10%) and Po=6.0 W (VDD=5.0V, RL=2, THD+N=10%).

(Excellent full bandwidth EMI suppression performance a) The radiation level of the original Active Edge Ringing and Overshoot Control Circuitry patent (AROC) is far below the FCC Part15 Class B standard; c) there is no inte

rference to the wireless communication sensitive modules in different frequency bands of the system, such as FM, CMMB, GSM, CDMA and Bluetooth; d) it reduces the radiation and conduction interference and reduces the sys

SC1113 is a class D audio power amplifier with high fidelity and ultra-low EMI. It has anti-jacking distortion function. Under 5V power supply, 10% THD + N, 4 load, the output power is 3.5W, maintaining high effici

ency in various audio terminal applications and providing high fidelity and low noise performance of class AB amplifier. AROC radiation and conduction interference suppression circuit makes SC1113 have exc

ellent full bandwidth and low radiation performance. The radiation level is far below FCC Part15 Class B standard without auxiliary filter design and output horn line length of 20 cm. SC1113's anti-crown distortion 

function can detect and suppress the output crown-cutting distortion (broken sound) caused by excessive amplitude of music and voice signals or voltage drop of batteries, significantly improve the sound quality,

 create comfortable listening enjoyment, and protect loudspeakers from overload damage. According to different requirements, the anti-cutting top has two modes: ACF-1 and ACF-2,

 corresponding to about 3% and 10% maximum THD+N, and the chip has ACF-Off mode. SC1113 output does not need filter network, and few external components save system space and cost.

 It is an ideal choice for portable applications. In addition, the built-in shutdown function of SC1113 minimizes the standby current, and integrates the functions of over-current protection, 

over-temperature protection and under-voltage abnormal protection.
