    Hi Chong Yu,

    But INA2141U and INA2141UA have same marking on page 11

    There is typo in the table found on page 11, which two part numbers should specify differently. 

    From TI store, the INA2141U and INA2141UA are specified differently, see the captured image below. INA2141U is the same as INA2141UE4, which it is higher grade than INA2141UA per the performance specification.

    Best,
