请问280049的比较器的正向输入端可以像负向输入端那样通过一个DAC人为的给一个值吗?或者有没有什么办法可以通过软件给比较器正向输入端一个特定的值?

你好,datasheet上有说明:
The positive input of the comparator can be driven from an external pin or by the PGA.
你好,应该是不可以的,datasheet上明确说明,正向输入端只能由外部或者PGA提供,反向输入端可以由外部或者DAC提供:
The positive input of the comparator can be driven from an external pin or by the PGA . The negative input can be driven by an external pin or by the programmable reference 12-bit DAC.
