INA170: Required CURRENT SHUNT MONITOR IC with Gain 100 or more

Part Number: INA170
Other Parts Discussed in Thread: INA169, , INA281, INA296B, INA240


We have been using this "High-Side, Bidirectional CURRENT SHUNT MONITOR" (MPN :INA170EA/2K5) in our designs as battery charging discharging- current measurement application for over 10 years.

At present In the production side now we couldn't get the part due to long lead time.

So plan to have a replacement part(1 to 1)   or with small design change(100 gain is preferred)

could you suggest some alternate MPN for the same. 

With  regard

  • Hello Praveen,

    I don't think we have any pin to pin compatible parts with the INA170....  But we do have various replacement options if you are open to a hardware change. If you only need unidirectional sensing, then you may be interested in the INA281 (it is fixed gain, but there is a 100 option).  The INA169 is more similar to the INA170, but is also older, so it may be a good idea to go with a newer device.

    If you need bidirectional, then the INA240 or the INA296B may be a good fit if you need >40V capability.  Otherwise you have many device options based on your requirements. I recommend using the product selection tool  found here: (for analog out devices, if you want digital there is a tool for that also). From this tool, you can select your desired parameters on the left and it will let you know which devices work for that (for example, select a gain of 100 and it will only show you devices that have a 100 gain option).
