NE5534A: EOL replacement

Mochi

Part Number: NE5534A
Other Parts Discussed in Thread: TLV9364

Hello,

We are seeing NE5534AD are Last buy process now and it is going to EOL announced by PDN# 20230522005.3

This OP-amp was employed on many of Audio application with a unique sound characteristics.

TI recommended replacement Op-amps is TLV9364, but it is CMOS type, sound characteristics completely different between bipolar NE5534A.

Would you please suggest us real substitutable Op-amp for 1ch bipolar input with external compensation pins for audio EE?

NE5534ADRG4 is still "Active" on web-page but can we order G4 device for a while from now?

Regards,

Mochizuki

Hello Mochizuki,

The NE5534ADRG4 is the replacement for the NE5534AD that is affected by RoHS/REACH. Usually this means Pb in the leads. The G4 version does not have Pb in the leads, but the core device is the same.

Hi Jerry,

Thank you very much for your prompt support.

That is good information that we can purchase NE5534ADRG4 as Pb free material.

I would like to confirm same other small things.

NE5534ADRG4 is not NRND or Last buy status. Can we use it for new design sockets as usual?
Is NE5532ADRG4 2ch version is same story?
What is difference between G4 device and E4 device? Both are Pb free, same tmp. Range, same die and same pricing?

Regards,

Mochizuki
