OPA2379: OPA2379AIDR – output unstable at high temperature

Guru 21045 points
Part Number: OPA2379

Hi Team,

 

Our customer use OPA2379AIDR but they confirm Output voltage fluctuates(unstable) more than 20mV at high temperature(around 40℃).

- Occurrence frequency is low

- Number of incidents is 1unit

- This phenomenon does not occur at the low temperature.)

 

They carried out A-B-A swap cross check.

At the result, the observed issue is not system related.

Therefore, they guess that the cause of this phenomenon is OPA2379AIDR and would like to know the root cause.

 

I would like to ask your advice on this matter.

Could you please let me know your e-mail address?

I can send the customer information(their circuit and waveforms).

 

I’m looking forward to hearing from you.

 

Regards,
