AD1838集成電路（IC）的編解碼器規(guī)格書PDF中文資料

AD1838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AD1838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。

PRODUCT OVERVIEW

The AD1838 is a high performance single-chip codec featuring three stereo DACs and one stereo ADC. Each DAC comprises a high performance digital interpolation filter, a multibit Σ-Δ modulator featuring Analog Devices’ patented technology, and a continuous-time voltage out analog section. Each DAC has independent volume control and clickless mute functions. The ADC comprises two 24-bit conversion channels with multibit Σ-Δ modulators and decimation filters.
