CXAR41313 is a high efficiency I2S input class D stereo audio power amplifier. CXAR41313 optional hardware or software I2C control. In BTL mode, it can provide 2*30W/8Ω power output; in PBTL mode, it can provide 75W/4Ω power output.Ca7嘉泰姆

The CXAR41313 has an over-temperature limiting function. When the internal temperature of the chip reaches the over-temperature limiting point, the CXAR41313 automatically reduces the gain, so that the IC can play continuously without interruption. In addition, the CXAR41313 has a power limiting function, one is an amplitude limiting function, which limits a certain output amplitude at the output end so that it does not damage the horn. The other is AGC anti-clipping distortion function, which can effectively improve the sound-breaking distortion caused by excessive input amplitude or reduced power supply voltage after being turned on.Ca7嘉泰姆

In addition, the CXAR41313 built-in shutdown function minimizes the standby current, and also integrates functions such as output over-current protection, on-chip over-temperature protection and power supply under-voltage abnormal protection.Ca7嘉泰姆
