PCM3003中文资料具有线性输出的低功耗立体声编解码器（H/W 控制）数据手册TI规格书

描述 Description

The PCM3002 and PCM3003 are low-cost, single-chip stereo audio codecs (analog-to-digital and digital-to-analog converters) with single-ended analog voltage input and output.

The ADCs and DACs employ delta-sigma modulation with 64-times oversampling. The ADCs include a digital decimation filter, and the DACs include an 8-times oversampling digital interpolation filter. The DACs also include digital attenuation, de-emphasis, infinite zero detection, and soft mute to form a complete subsystem. The PCM3002 and PCM3003 operate with left-justified (ADC) and right-justified (DAC) formats, while the PCM3002 also supports other formats, including the I2S data format. The PCM3002 and PCM3003 provide a power-down mode that operates on the ADCs and DACs independently.

The PCM3002 and PCM3003 are fabricated using a highly advanced CMOS process, and are available in a 24-pin SSOP package. The PCM3002 and PCM3003 are suitable for a wide variety of cost-sensitive consumer applications where good performance is required.

The PCM3002 programmable functions are controlled by software. The PCM3003 functions, which are controlled by hardware, include de-emphasis, power-down, and audio data format selections.

简介

PCM3003属于集成电路（IC）的编解码器。由TI制造生产的PCM3003编解码器编解码器是用于通过压缩和解压缩来转换数据的半导体器件。数据压缩可提高传输速度并减少存储空间。某些编解码器提供高达 32 位的分辨率，并且分别提供多达 6 个或 8 个模数转换器和数模转换器。除三角积分调制外，还有 I2C、I2S、SPI、串行、HDA、S/DIF、PCM、USB、AC'97 和 SLIMbus 数据接口。
