NE5534: The customer is looking for TI device which can replace NJM5534D.

Hello Kazuya-san,

TI NE5534DR is also end of life. For what purpose is pin 5 used? I have same question for pins 1 & 8. Can you share a partial schematic?

Perhaps we have a replacement that does the same thing as pin 1,5,8 but does it internally.

Hello Ron,

Thank you very much for your reply.

Unfortunately the customer doesn't want to disclose at this moment.
They want to know the equivalent circuit of OPA134PA.

Do you have the equivalent circuit?

Thank you again and best regards,
Kazuya.

Hello Kazuya-san,

The best options to replace the NJM5534D are either the NE5534 or the modern OPA1677. We don't have an equivalent modern device that pins out compensation or balance features.

Best Regards, 
Chris Featherstone

Hello Chris,

Thank you very much for your reply.

I proposed them to use OPA1677. But I knew that they needed DIP 8pin package device because NJM5534D is DIP 8pin.
I think NE5534P is only device which can replace NJM5534D. 
Is my thought correct?

Thank you again and best regards,
Kazuya.

Hello Kazuya-san,

Yes that is correct. One possibility would be to solder a modern surface mount component to our DIP adapter board. Although this would be challenging in high volume.
