OPA4189: OPA4189 Termination

Hi Winsbert,

The device can be manufactured with NiPdAu termination finish?

In the material content link below, I do not see the NiPdAu plating option currently. The lead frame alloy composition is shown below. I believed that NiPdAu finish was used. Some other chopper op amps may be different. it is possible that it depends on the manufacturing site.

The link below is our chopper amplifiers' selection.

If you have other questions, please let me know.

The purpose of the question is to provide the direction on a special request for a large amount of part with the termination finish of NiPdAu. is there a person or department were it can be addressed and get an agreement if this can be achieved?

I can ask the marketing engineer and see if this is doable. Personally I am not sure, since this is the current default build material. What are the qualities you are talking about so I post the inquiry to the team?

the amount i would need is 1000pcs

Hi Winsbert, 

I was told that NiPdAu lead frame is somehow created a Seebeck effect in this part and that is why it has different lead frame finish.

Here are other quad chopper amplifier selection.
