DAC的zero scale和midscale的疑问
[复制链接]
图片是DAC芯片(AD5676)的spec,有以下几个疑问:
1. zero scale和midscale分别是什么意思?
2. zero scale模式和midscale模式分别有什么优缺点?
3. 我们上电一般是让DAC处于zero scal模式还是midscal模式呢?
3. Note that this is outside the linear region of the DAC是指DAC上电到这种模式,DAC不在其线性范围内吗?
4. The output remains powered up at this level until a valid write sequence is made to the DAC?“at this level”是指掉电前的电平吗?
请各位大佬帮忙指导,谢谢!
