CXAR41201是一款单桥音频功率放大器，专为便携式通信设备应用和移动电话中的高要求应用而设计。CXAR41201YPS8能够将2.4W的连续平均功率传输到4Ω负载中，通常由5伏电池电压产生10%的失真（THD+N）。它工作在2.5V到5.5V的电源。
当对SHDN引脚施加V+时，激活CXAR41201电源关闭模式（ISD=0.07μA典型值）。由于CXAR41201不需要输出耦合电容器、自举电容器或缓冲网络，因此它非常适合需要最小体积和重量的低功耗便携式系统。
CXAR41201是单位增益稳定的，可以通过外部增益设置电阻器进行配置。此外，CXAR41201具有内部热关机保护机制。
CXAR41201有绿色SOIC-8和SOIC-8（外露衬垫）封装。它在-40℃到+85℃的环境温度范围内工作。

产品概述 返回TOP
The CXAR41201 is a mono bridged audio power amplifier that is designed for portable communication device applications and demanding applicationsin mobile phones. CXAR41201YPS8 is capable of delivering 2.4W of continuous average power into a 4Ω load with typically 10% distortion (THD+N) from a 5V battery voltage. It operates from 2.5V to 5.5V power supply.
The CXAR41201’smicro-power shutdown mode (ISD = 0.07μA TYP) is activated when V+ is applied to the SHDN pin. Since the CXAR41201 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is ideally suited for low power portable systems that require minimum volume and weight.
The CXAR41201 is unity-gain stable and can be configured by external gain-setting resistors. Additionally, the CXAR41201 features an internal thermal shutdown protection mechanism.
The CXAR41201 is available in Green SOIC-8 and SOIC-8 (Exposed Pad) packages. It operates over an ambient temperature range of -40℃ to +85℃.
