Hi Team,

The customer would like to know the difference between INA2143U and INA2134UA. I see the performance parameters on page2 and 3 of the datasheet

for INA2134UA are shown " * ".

What is the difference between INA2143U and INA2134UA?

Would you send me some specific performance parameters for INA2134UA?

Hello Mickey,

According to the data sheet, the "A" version has some min/max specification with different values. For example, the maximum offset voltage spec for the "A" version is +/-500uV, while it is +/-250uV for the "non-A" version. This correlates to the final test limits. For example, it is possible to obtain an "A" version with 400uV of offset, but you should not receive a "non-A" version with 400uV of offset.

Please note that our team is on holiday until early next year, so any follow up questions will be delayed. We appreciate your patience during the holidays.
