Dear Specialists,
My customer is considering OPA2182 instead of OPA2277 and has a question.
I would be grateful if you could advise.
---
Regarding OPA2277 datasheet, it is described Channel Separation at DC.
However, it is not described OPA2182 datasheet.
Could you please let us know channel separation at DC of OPA2182.

I appreciate your great help in advance.
Best regards,
Shinichi
Hi Shinichi,
look at the "crosstalk" specification on page 9 of datasheet.
150dB translates to 0.032 µV/V.

Hi Shinichi-san,
Could you please let us know channel separation at DC of OPA2182.
Please see Kai's comments, see the captured image below.
If you have additional questions, please let us know.
Best,
Raymond
Adding to other comments, there is graph of OPA2182 channel separation - see below. Having said that, -150dB at dc applies only for 10kohm or lighter load - heavier load will result in a lower channel separation number at dc.
Hi Kai, Raymond and Marek,
Thank you for your quick reply.
I am happy to receive a lot of advice from you.
I'll share your answers with the customer.
I appreciate your great help and cooperation.
Best regards,
Shinichi
