产品概述 返回TOP
The CXAR41113 is a monolithic integrated circuit, which provides precise DC volume control, and a stereo Class-D audio power amplifiers capable of producing 9W into 8W (12V) with less than 10% THD+N. The attenuator range of the volume control in the CXAR41113 is from 36dB (VVOLUME =5V) to -40dB (VVOLUME =0V) with 32 steps. The advantage of internal gain setting can be less components and PCB area. The circuitries of both thermal and the over-current protections are integrated in the CXAR41113. It protects the chip from being destroyed by over temperature and over current failure. To simplify the audio system design, the CXAR41113 combines a line output for external headphone driver with volume control and a 5V regulator for external headphone drive, where the speaker output can be switched off by the headphone jack’s switch pin that connects to the CXAR41113’s mode pin as shown in the application circuit
