关于FXN8361QX轴模拟输出的问题

[yongjunjiang]

在使用FXLN8361QX轴输出，在X轴输出端只接0.01u电容，0g时输出电压为0.754V，通过100k电阻接入LM324反相端0g时输出电压降为0.683V。

Hi Yongjun,

Looking at your schematic, there is basically a voltage divider with the internal 10 kΩ resistor causing this voltage drop. To avoid this, I would suggest using a low input offset rail to rail op amp to act as a buffer.

I hope it helps.

Tomas
