Excuse me how much is the voltage sampling resolution ina219 and ina199.-CodePudding

Excuse me how much is the voltage sampling resolution ina219 and ina199,
For example, 0.01 euro resistance on 1 a current resistance on 10 mv can tell?
Have a problem, can be in INA219 0 v to 26 v range sensor bus partial pressure of the sentence refers to the flow resistance voltage above 36 v, thank you.

Lz you can measure,

ADC reference voltage 5 V, for example, while using 10 high-resolution ADC, minimum resolution is 5 V/1024=0.0048828 V, you have 10 mv can tell, but if you only have 2 mv, the resolution not to come out

CodePudding user response:

Points on the compressive resistance of only 10 ma, the resolution is 0.002441, so high precision can reach? The device on both ends of two detection foot meet resistance, how to detect the bus voltage?

I don't know what is your so-called bus voltage
