AD73322L and its interface design with DSP5416

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 principle of chip AD73322L and its interface design with DSP5416.
