AD73322L and its interface design with DSP5416

芯片AD73322L是AD公司推出的低成本,低功耗CMOS通用双通道模拟前端。它具有两个16位的A/D转换通道和两个16位的D/A转换通道,输入输出速率和增益可编程,ADC和DAC的信噪比均达78dB,可以同时进行A/D和D/A转换。本文介绍了芯片AD73322L的性能特点,功能、基本原理及其与DSP5416的接口设计。

The chip AD73322L is low cost, low power CMOS general -purpose dual analog front end which is introduced by AD Company. It has two 16-bit A/D convert channels and two 16-bit D/A convert channels,its input and output speed and gain are programmable,the SNR of both ADC and DAC can reach to 78dB.The A/D and D/A converting can be at the same time. This paper has introduced the performance characteristic, function, basic pdnciple of chip AD73322L and its interface design with DSP5416.
