Hello,

Please support for following request from customer.

Please give us the distribution data of offset voltage at Low, room and high temperature.

Customer needs this information to fix their problem occurring under maximum offset voltage specification of datasheet.

Best Regards.

Toshio-san,

The "A" grade is the most accurate VIO version of LM2903.

Here is some data. All data in mV units

5V			32V
TEMP	Mean	StdDev	TEMP	Mean	StdDev
-40	-0.732	0.486	-40	-0.228	0.517
25	-0.713	0.461	25	-0.120	0.499
125	-0.475	0.338	125	0.203	0.401

Can the application be changed such that it is not so sensitive to VIO?

Hello Ronald-san,

Thank you very much for your quick support.
I'm sorry, they can't say details about application.

Customer needs temperature characteristics of bias current.
So, could you send me the same kind of distribution data of bias current?

Best Regards.
