CXAB4108是一个桥接音频功率放大器，能够从5V电源以0.5%（THD）的功率向82kP负载提供通常为1.1W的连续平均功率。Boomer音频功率放大器是专门为提供高质量的输出功率与最少的外部组件。由于CXAB4108不需要输出耦合电容器、自举电容器或缓冲网络，因此它可以选择性地适用于低功耗便携式系统
CXAB4108具有外部控制、低功耗关机模式以及内部热关机保护机制
单位增益稳定的CXAB4108可以通过外部增益设置电阻器进行配置。
1W时1kHz时的THD连续平均输出功率为82KP0.5%
在10%THD+N时，在1khz时输出功率为82kp1.5W
关断电流0.6μA

产品概述 返回TOP
The CXAB4108 is a bridge-connected audio power amplifier capable of delivering typically 1.1W of continuous average power to an 82KPload with 0.5% (THD) from a 5V power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. Since the CXAB4108 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is optionally suited for low-power portable systems 。
The CXAB4108 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism。
The unity-gain stable CXAB4108 can be configured by external gain-setting resistors.
