CXAR41186是一个立体声音频功率放大器，具有差分输入。在一个5V电源上工作，它将每个通道132mW的连续均方根功率传输到16Ω负载中，通常为0.1%THD+N。放大器增益通过每个输入通道两个电阻器进行外部配置，不需要外部补偿。
CXAR41186旨在最大限度地提高移动电话等便携式通信设备应用程序的音频性能。便携式应用要求音频功率放大器具有最少的外部组件，可在单个2.7V至5.5V电源下工作。
CXAR41186具有外部控制、主动高、微功耗关机模式。此外，CXAR41186具有内部热关机和短路保护机制。
CXAR41186有绿色MSOP-10包装。它在-40℃到+85℃的环境温度范围内工作。

产品概述 返回TOP
The CXAR41186 is a stereo audio power amplifier with differential inputs. Operating on a single 5V power supply, it delivers 132mW of continuous RMS power per channel into a 16Ω loads with typically 0.1% THD+N. Amplifier gain is externally configured by means of two resistors per input channel and does not require external compensation.
The CXAR41186 is designed to maximize audio performance in portable communication device applications such as mobile phone. The portable application requires audio power amplifier has minimum of external components and can operate from a single 2.7V to 5.5V power supply.
The CXAR41186 features an externally controlled, active-high, micro-power consumption shutdown mode. Additionally, the CXAR41186 features an internal thermal shutdown and short circuit protection mechanism.
The CXAR41186 is available in Green MSOP-10 package. It operates over an ambient temperature range of -40℃ to +85℃.
