谈一下我个人的理解:VADC(Versatile Analog-to-Digital Converter):多功能模数转换器,就是我们平时用的模数转换器,有许多的通道,具体的功能可参照用户手册;DSADC(Delta-Sigma Analog-to-Digital Converter):专门用于旋变位置解码,内部集成了旋变激励信号发生单元(Carrier Generator) ,可以通过编程得到自己想要的正弦信号,同时可以对反馈信号进行同步采样,通过读取内部寄存直接得到正余弦电压转换结果,简单点,这个模块可以通过软件来解码旋变位置,不需要专门的旋变位置解码芯片了(如:AD2S1210)

VAD C只是普通的ad采样通道,dsadc是专门为旋变解码设计的

转换速率有很大的差异:SAR-ADC为1M左右,DS-ADC为20M左右

vadc是逐次逼近型,速度快、精度稍差;DSADC是积分型,速度慢,精度高。
