Nice to meet you. OPA348-Q1 is used in customer. This project is already mass production. There is one pcs of OPA348-Q1 was broken on End customer side. Could you give us some recommendation? Thanks.
Here are the question from customer side:
1. Device Life. How long the device can work normally under the datasheet condition?
2. Failure Analysis.
The device still can work,, but the offset of V+ is 0.19V. When VDC is 0V, V+=0.19V, Vout =0.7V. When V+= 1.0 V, Vout = 1.51V.
Which function part may be damaged? Could you share the internal function for OPA348-Q1? Thanks.
