INA216: current sense product suggestion

Part Number: INA216
Other Parts Discussed in Thread: INA186, INA190

Hi sir,

I wanna select a current sense,

My circuit current is wide range from 10mA to 2A.

voltage is 1.1V 1.5V 2.5V and so on.

is INA216 meet my requirements?

If not, can you suggest a recommended product?

Thank you for your valuable suggestion.


  • Frank,

    Can you share what you mean by "voltage is 1.1V 1.5V 2.5V and so on." Are you saying that your maximum voltage that you can supply the amplifier with is a maximum 2.5V?

    Based on the lower range of measurement in the mA range, as well as potentially the limited voltages above, I would recommend looking at the INA186 or INA190. These devices are capable of operating down to a 1.7V supply range, and have input bias currents in the picoamp range, which will help reduce error in the lower decades of your measurement.
