产品概述 返回TOP
The CXAR41266 is a 3W high efficiency filterlessmono class-D audio power amplifier in a SOP8 package,it has high PSRR and differential input that eliminate noise and RF rectification.The CXAR41266 features like 90% efficiency and small PCB area make the CXAR41266 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 CXAR41266 features short circuit protection and OTP(over temperature protection) thermal shutdown and UVLO(under voltage lockout).he CXAR41266 is available in SOP-8 package
