Question Suggestion for Quad Opamp PDIP Package

Hi !!

I need a good sounding quad opamp, in dip package.

Mainly I use OPA134 series, but OPA4134 isn't avaliable in DIP package anymore. I like this opamp very very much, it's very realiable, and not very costly.

It CAN'T be more expensive than an OPA4134. What would you suggest?


Thank you very much !


Best Regards,


Fernando

Hello !

I appreciate the answers

OPA2134 is a dual version, I need a quad version.

OPA4134 + DIP adapter is very high cost, as the adapter costs more than 5usd.

MC33179 is much more cheaper than OPA4134, if it have a good sound, will be a GREAT solution, I'll buy and test it. But I want more suggestions

Opa 4228 is very expensive...

But I'm asking myself... WHY they don't make 4134 in dip package anymore????


Thanks !!!


Best Regards

MC33179 : 5Mhz, 2v/s slewrate

134 series: 8Mhz, 20v/s slewrate.

TL074, 3Mhz, 13v/s slewrate

LM837 (NE5532 Quad modern): 25Mhz, 10v/s slew rate.

I think that talking about specs, the LM837 is the best comparing to 134 series...

Talking about the SOUND, how slew rate and frequecy affects the sonics?


Best Regards !

I think you can guess. If they can't sell any OPA4134 in DIP they won't manufacture those either. The answer is easy: The market!

Well maybe try makeing a dual Opamp to Quad Opamp adapter that will convert 2 Dual 2134 into a single 4134......

I recently designed a Two Single Dip8 to Dual Dip8 adapter so I could use a couple OPA627 in the Dual Opamp Footprint and they work Great.......


Just a Thought.....
