INA125: Parameter difference between A version and without A version

Anna

Part Number: INA125

Hi Dear,

Regarding INA125UA and INA125U, what are the specific differences in parameters between versions with and without A? Is there a detailed explanation?

Can INA125UA completely replace INA125U?

The differences are shown in the columns at the right on p. 2/3 of the datasheet: errors (offset, CMR, gain, voltage reference) and bias current are higher.

(Both models are currently out of stock.)

Hey Anna,

As Clemens mentioned the differences are highlighted on the datasheet table. Let me know if I can be of further assistance. Please reference this post:

Hi Dears,

Do you have any relevant test data regarding the performance comparison of these two materials?

INA125U is out of stock, and the customer wants to temporarily replace it with INA125UA. They need some more detailed information

Hi Anna,

The tables in the PDS are measured values and highlight the performance differences. The stars within the table for the UA mean that the specification is the same as the U. If they are not the same the numbers are given to highlight the difference. What information is the customer looking for outside what is given in the product datasheet? Providing test data would require us to have a formal NDA in place that our field engineers would help with if needed.
