LM258A datasheet typ/max value is 15uV/C. Is this for the full temperature ranges from -40 to 105? If no, what is the offset voltage min / max across the full temp range?

[Tom BOCCHINO]

If the offset voltage drift is above 15uV/°C is there any tighter part available? 

[Antoine Cros]

Hello,

Offset voltage drift is defined between 25°C and the extrema of the temperature range. This means that, for LM258A, the maximum offset drift is 1.2mV over the whole temperature range.

If this drift is too large for your application, we can advise a more precise part, depending on your other application requirements.

Best regards
