[原创] Maxim MAX13335E－6E汽车高保真立体声音频输入方案

Maxim公司的MAX13335E/MAX13336E是用于汽车的高保真立体声音频输入放大器,具有双路低噪音可编增益放大器,采用全差分(7VRMS)和准差分(3.5VRMS)输入信号以及通过I2C接口控制的诊断功能,工作电压3.3V或5V,28V到-16V容差输入,共模输入-5V到+11.5V,主要用在汽车无线电前置单元,RSA/RSE,连接模块和汽车远程信息处理.本文介绍了MAX13335E/MAX13336E主要优势和特性,框图和应用电路,以及评估板MAX13335E EVK主要特性,电路图,材料清单和PCB设计图.

The MAX13335E/MAX13336E are high-fidelity stereo audio input amplifiers designed for automotive applica­tions requiring audio-level detection and/or jack sensing capability. The devices feature a dual-channel, low-noise, program­mable gain amplifier that accepts fully differential and quasi-differential input signals with diagnostics capability controlled through an I2C interface. The devices’audio receiver can also pair with the MAX13325/MAX13326 audio transmitter to form a complete differential audio link in automotive systems.
