The CXAR41267 is a 3W high efficiency filterlessmono class-D audio power amplifier in a MSOP8 package,and a DFN package that requires only Three external components,it has high PSRR and differential input that eliminate noise and RF rectification.The CXAR41267 features like 90% efficiency and small PCB area make the CXAR41267 class-D amplifier ideal for cellular handsets. A low noise, filterless PWM architecture eliminates the output filter, reducing external component count, system cost, and simplifying design. The CXAR41267 features short circuit protection and OTP(over temperature protection) thermal shutdown and UVLO(under voltage lockout).The CXAR41267 is available in MSOP-8, and DFN2X2-8 package.
