车载应用中的高品质，高性能音频CODEC解决方案
新唐科技在全方位布局智能车载应用市场，深入车载音频多样化应用场景，持续推出音频的新产品及解决方案，发布高性能指标的音频CODEC和DAC新品。
伴随着汽车电子进入“智能座舱”时代，汽车智能化趋势成为行业热点，车载应用对音频产品的技术提供商提出越来越高的功能要求。
新唐科技的CODEC路线图如下：
*SR: Sampling Rate
新唐科技严格执行汽车行业规范标准，为车载应用提供符合AEC-Q100认证的产品，同时车规与工规物料可进行P2P，车规级音频编解码芯片分别有：Stereo(NAU88U22)和Mono(NAU88U10)。
车载系统常见的T-BOX(eCall)应用，新唐科技提供的高信噪比多功能CODEC型号，除满足音频ADC/DAC编解码，内置特定功能DSP，支持PCM和I2S界面，最高采样频率达48KHz。
而跨入智能驾舱时代，“空间音频”和“沉浸式听音”的需求快速提升，进一步展现汽车厂商的硬件和软件实力，从应用上加强对关键器件的挑选(如：音频编解码，音频功放，音频DSP，等)至关重要。
智能驾舱拾音，行车记录仪，语音识别，听声辨位，降噪处理，将模拟MIC信号转换成数字信息，再提供给音频处理单元或车载SOC，这类应用中对信噪比和音频采样频率指标要求高；新唐可提供多款高性价工规和车规型号；“网红”型号NAU85L40B，多路ADC通道，支持多路复用(TDM)PCM输出，QFN28L封装。
车载前装应用中常将SOC或DSP输出的数字信号转换为模拟信号给后端模拟功放; 而车载后装应用中，以改装音箱中较为常见DAC的应用，常根据后端模拟功放的通道数，决定前端DAC的通道配置。NAU8421为24bit立体声DAC，高信噪比128dB，QFN32的封装。
