​HelloA last point to check. It is the current sense you have to measure. As the lowest potentential is the power supply -5V, the current should flow from ground to power supply isn't it? So in this case, connection should be like this:If you need to...

HelloThe shunt connected between load and ground can have an impact , if there is large current spike, that may perturbate the GND.Note that the same thing can happen with High side configuration, large current spike will impact the supply of the pow...

Thanks for the clarificationNevertheless let me still clarify this point:Yes may be low side current sense is not possible in our application but we want to confirm from your side.A low side configuration is the simplest configuration as you can dire...

helloJust to be sure to understand correctly your point about power supply.Do you mean the current sensing and also the ADC will be powered with a negative power supply as well in the range of [-5V:-2V]?like the principle schematic attached.It also m...

​HelloWe can firstly have a look on two different way to measure a current with a negative common mode voltage.The simpler is to use a current sensing with an integrated gain able to work in this manner. It can be our TSC2012 product which accept a ...
