产品概述 返回TOP
The CXAR4191 is a stereo, fully differential Class-AB audio amplifier which can operate with supply voltage from 2.4V to 5V and is available in a TQFN5x5-20A package. The built-in feedback resistors can minimize the external component counts and save the PCB space. High PSRR and fully differential architecture increase immunity to noise and RF rectification. In addition to these features, a short start-up time and small package size make the CXAR4191 is an ideal choice for LCD TVs and notebook PCs and Portable devices. The CXAR4191also integrates the de-pop circuitry that reduces the pops and click noises during power on/off and shutdown mode operation. Both Thermal and over-current protections are integrated to avoid the IC being destroyed by over temperature and short-circuit. The ACXAR4191is capable of driving 3W at 5V into 3W speaker
