Part Number: INA240EVM

What is the maximum current carrying capacity INA240EVM designed for? i.e. If I use one of the four boards, how much current can be handled by the PCB?

Hello Ruchit,

Thank you for your interest in the INA240EVM. Presuming you operate at room temperature, the device has a margin of 100 ᵒC under which it is within recommended operating conditions (-40ᵒC to 125ᵒC). The current will be limited by the narrowest region of the trace. The most narrow region is 129 mils wide. Thus for a DC current, the max recommended current would be 7.86A. If you have different temperature conditions, I would recommend using the following online trace calculator: https://www.4pcb.com/trace-width-calculator.html
