Hello Everyone,
I am trying to implement a shunt resistor on the high side.
I am finding it difficult to select the differential amplifier/opamp which amplifies the the voltage across the shunt.
Here are my requirements.
Input voltage : 150v DC.
Range of current to be measured : 0 to 50A
Vcc of opamp cannot be more than 5v
I searched many places but my main issue is the Commom mode input voltage range,
I couldn't find any opamp that can handle the high voltage.
If anybody knows of such an amplifier please share the part number.
Many thanks,
AK
