The CXAR4184 is a Mono, fully differential Class-AB audio amplifier which can operate with supply voltage from 2.4V to 5V and is available in MSOP8, MSOP8P, or TDFN3x3-8 package. The built-in feedback resistors can minimize the external component count 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 startup time and small package size make the CXAR4184 an ideal choice for Mobil Phones and Portable Devices. The CXAR4184also 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 to be destroyed by over temperature and short-circuit. The CXAR4184is capable of driving 3W at 5V into 3W speaker
