INA199: Zero-Current Condition (compared to INA181)

$

Part Number:INA199

I initially specified INA181 current sense amplifier for current measurement in one of my designs. However, the datasheet seems to indicate that a zero-current condition would yield an offset voltage on the output because of the non-zero common-mode voltage on the input of the amplifier.

 

From my understanding, the INA199 does not have this problem and would yield the same output regardless of the common-mode voltage.

 

Would you be able to confirm this? Thanks!

Thanks,

Brian Angiel
