4CH OUTPUT STEREO AUDIO PROCESSOR WITH 4 STEREO INPUTS AND TONE/VOLUME CONTROL

DESCRIPTION The SC7312 is a volume, tone (bass and treble), balance (left/ right) and fader(front/rear) processor for quality audio applications in car radio and Hi-Fi systems. Selectable input gain and external loudness function are provided. Control is accompli

四路立体声输入带音调和音量处理的数控四声道音频处理器

 SC7312是一块具有音量、音调（低音、高音）、平衡度（左、右）和响度（前、后）控制的音频处理电路，适用高品质的汽车收、放音机和高保真的音响系统中。该电路提供了输入增益选择和外部响度控制功能。所有的控制均通过可与微机连接的串行I2C总线来操作；通过外接阻容网络和内部运放的配合，可设置各种交流幅频特性。由于采用了高性能的CMOS工艺技术，实现了低失真、低噪声和低直流电平漂移。SC7312的封装形式为塑封32引线的扁平式（SOP）封装。 ·含有输入多路选择器  -四路立体声信号输入  -输入增益可设置以与各种信源进行最值匹配 \n·四声道衰减器  -四个声道可独立控制。对平衡度和响度进行每级1.25dB的衰减和提升。  -独立的静音控制功能。 \n·所有的功能均通过串行I2C总线控制 \n·有响度控制功能 \n·音量控制每级1.25dB \n·高音和低音控制 \n·输入与输出端可与外部均衡器和噪声抑制电路匹配;
