AD1928集成電路（IC）的編解碼器規(guī)格書PDF中文資料

AD1928屬于集成電路（IC）的編解碼器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD1928編解碼器編解碼器是用于通過壓縮和解壓縮來轉(zhuǎn)換數(shù)據(jù)的半導(dǎo)體器件。數(shù)據(jù)壓縮可提高傳輸速度并減少存儲空間。某些編解碼器提供高達(dá) 32 位的分辨率，并且分別提供多達(dá) 6 個(gè)或 8 個(gè)模數(shù)轉(zhuǎn)換器和數(shù)模轉(zhuǎn)換器。除三角積分調(diào)制外，還有 I2C、I2S、SPI、串行、HDA、S/DIF、PCM、USB、AC'97 和 SLIMbus 數(shù)據(jù)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.
