AD1838A集成电路（IC）的编解码器规格书PDF中文资料

AD1838A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AD1838A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 AD1838A 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
- 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
- modulators and decimation filters.

The AD1838A also contains an on-chip reference with a nominal value of 2.25 V.
