REF4132-Q1: REF4132-Q1

Hello,

Below are my responses to your questions:

How to calibrate the temp drift? And in the design tool, the calibration is about the temp?

Can you help to show how to calibrate about REF4132-Q1? Thanks in advance.

Please note that in the tool, calibration only excludes initial accuracy and solder shift, and does not consider calibration from temperature drift. Multipoint calibration should be used to calibrate the temperature coefficient. More details on how this is done can be found in the "Calibration" section (section 5) of "Voltage Reference Selection and Design Tips For Data Converters" found here: https://www.ti.com/lit/an/snaa320b/snaa320b.pdf

What temperature drift are you trying to reach? What range of temperatures are important for your application?

How to use the line/regulation?

Load regulation is how the output will vary as the input voltage varies. Load regulation is how the output will vary as the output current of REF4132-Q1 varies.

the first line and the second line only difference is the tpy. value and max. value?

This is correct.

Thanks,
