Hi ALL,
when i am testing the current of VCCA,i found that VCCA has 2mA current, and when i conect 2A2 to gnd, zhe total current of VCCA decrease to 0.2mA.
The qustion is :2A2 is an output pin(in this apllication),why i confirm an output CMOS device will decrease VCC current?
If i confirm a vin state of CMOS device,the VCCA current decreased,that i can undestand.
