Current sense parts recommendation inquiry.

Other Parts Discussed in Thread: INA181

The customer wants to use the shunt-type inline current sense method, but there is an inquiry about the applied device.

Is there any device you would recommend considering the delivery date and unit price?

The supply voltage is planned to be supplied as 3.3V, and a reference voltage of 1.65V will be applied to be used as Bi-Directional.

Please check. Thank you.

    Hello,

    I can only speak on unit price and TI store inventory. Using the parametric search on the current sense amplifier with analog output page on TI.com the cheapest bi-directional part with inventory not equal to 0 will be the INA181.

    If you have any other questions please reply

    Regards,

    Castrense
