OPA2313: Noise density drift of OPAx313

Iwata Etsuji

Part Number: OPA2313

Hi team,

My customer is doing the worst case analysis for noise density of OPA2313.

Now they are asking how much could the noise density of OPA2313 change with temp change.

How should we calculate such a thermal drift of noise density ?

Is it within 6.6sigma, where 1sigma=typ value...?

Best regards,

Hello Iwata-san,

Please see rule of thumb #2 in the attached article for an explanation about how noise increases with temperature.
