INA138: Can it measure 200uA ~ 1A range ?

Part Number: INA138


We are looking for a solution to measure 200uA ~ 1A range. is INA138 suitable or other suggestion ? 

  • PYTsai,

    the resolution you are looking to measure here is 5000:1. That is going to be a challenging design for any amplifier. The answer here isn't black and white, and there are several things we need to know about the system. Could you share any info on the following:

    - What supply voltage do you plan to use?

    - What value of gain are you looking to implement in the system?

    - What level of error is acceptable in the signal?

    - What size shunt do you plan to use, and can the system tolerate the thermals generated by that choice?
