Overview
SC3116 is a high-efficiency Class D audio power amplifier. In BTL mode, it can provide 2*30W/8Ω power output; in PBTL mode, it can provide 80W/4Ω power output.
SC3116 has an over-temperature limiting function. When the internal temperature of the chip reaches the over-temperature limiting point, SC3116 automatically reduces the gain so that the IC can play continuously without interruption. In addition, SC3116 has a power limiting function, one is the amplitude limiting function, which limits a certain output amplitude at the output end to prevent damage to the speaker. The other is the AGC anti-clipping distortion function. When turned on, it can effectively improve the sound-breaking distortion caused by excessive input amplitude or reduced power supply voltage.
In addition, SC3116 has a built-in shutdown function to minimize the standby current. It also integrates functions such as output overcurrent protection, on-chip over-temperature protection and power supply under-voltage abnormal protection.
