AD1928集成电路（IC）的编解码器规格书PDF中文资料

AD1928属于集成电路（IC）的编解码器。由亚德诺半导体技术有限公司制造生产的AD1928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。

GENERAL DESCRIPTION

The AD1928 is a high performance, single-chip codec that provides two analog-to-digital converters (ADCs) with differ ential input and eight digital-to-analog converters (DACs) with single-ended output using the Analog Devices, Inc., patented multibit sigma-delta (Σ-Δ) architecture. An SPI port is included, allowing a microcontroller to adjust volume and many other parameters. The AD1928 operates from 3.3 V digital and analog supplies. The AD1928 is available in a 48-lead (single-ended output) LQFP package. Other members of this family include a differential DAC output and I2C® control port versions.
