max471 current sense IC

(1/2) > >>

As replacement components for two circuits I designed and built, I am looking to buy more DIP MAX471CPA current sense IC's. Digikey no longer has them in stock. Anyone know where I can find some?

Unfortunately, they seem to be a discontinued product:

They have 'replacement' versions, but none of them are in a DIP package.  :'(

Assuming I cannot get a replacement with the same pinout . . . anyone know of any other current sense IC's with a DIP package?

I found this available at Digikey:
but unfortunately it is also discontinued, with 'replacement' versions that also wont work . . .

H&R Enterprises lists on their inventory search page that they have 7683 of them in stock. They're a parts "headhunter" firm, that specializes in obsolete parts - so expect to pay a premium for anything you get from them. I'll try to ask my power supply IC "guru" if he knows of any pin-for-pin equivs in an 8-Dip package, If I can get in touch with him before the New Year.


Yea I found that on findchips.com after I made this post. I sent a request, hopefully I get lucky. They had originally cost $6.20 each, so Im willing to pay around that . . .

If not a pin for pin (worse case), at least an 8 pin DIP that does the same thing.

just got this email from Maxim:

"Dear Sir,
Thank you for your interest in Maxim Integrated Products. As of now, there is no replacement for MAX471 in DIP package.

That isn't unusual for MAX parts - they do tend to make a lot of parts that are Sole-Source items. Still - I wouldn't give up quite yet. Maxim isn't necessarily likely to let you know if one of their competitors offers a similar product in the same package.
