说明：  S42L52 是一个 24 位 CS42L52 低功耗立体声编解码器，因其高度集成和高性能的音频输出而闻名。CS42L52 能够为外部扬声器的每个声道提供高达一瓦的高效 D 类放大，或者提供充足的能量向立体声耳机的每个声道输入 44 毫瓦功率，这使得 CS42L52 能够非常灵活地通过单电源运行其核心，可使 D 类放大器和电池直接连接，从而实现更高效的运行。这种 IC 对于便携式消费电子产品的作用非常理想，如：便携式媒体播放器、游戏设备、MP3 播放器相关产品、IC 录音机、数码相机和摄像机等。 这个是工程中实际使用的程序。
(S42L52 is a 24-bit CS42L52 low-power stereo codec, due to its highly integrated and high-performance audio output is known. CS42L52 able to provide external speakers for each channel up to one watt high efficiency Class D amplification, or to provide sufficient energy to the stereo headphones 44 milliwatts per channel input power, which makes CS42L52 can be very flexible single-supply operation its core, will enable Class D amplifier and battery is connected directly to achieve a more efficient operation. This IC for portable consumer electronics products, the role is ideal, such as: portable media players, gaming devices, MP3 players, related products, IC recorders, digital cameras and camcorders. This is the actual use of project procedures.)
