Smd Opa4134

[Funnel]

In search of two opa4134’s. if you know where some may be acquired before 2023 it would be greatly appreciated.

What are you using them for? The OPA1644 is a suitable replacement in many applications.

Noted! That was my other question. It’s two vfe sps builds. I think it replaced the tle074 in those circuits

Which builds? Note that the TLE2074 comes in a SOIC package. I'm using a OPA1644 in lieu of a OPA4134 in the pinball.

Sorry, the change from v2 to v3(sps) went from tle 074 to opa4134. At least that’s what I can tell.

Slightly better sounding part in many cases anyway in my book, at least judging from using the dual equivalents. OPA1642 and 1641 just came back in stock at Mouser recently, hopefully 1644 have as well.

They were in stock last I checked. They aren’t available on the TI site though.

I see. Note that the part is TLE2074. The “2” sneaks in there.

EDIT: It's also a 16-pin SOIC package. So, it won't work as a replacement for a 14-pin package. I suggest going with the OPA1644.

Thanks I’ll take a look at what’s in stock. I’m more hesitant to try components when I can’t socket them. So I appreciate your suggestions!

 

[Funnel]

Alright, thanks again I finally placed an order for the 1644’s. I will eventually finish these pedals… it may take another 6 months but I will finish them.

I meant to add this earlier: if you have the clearance, you can use the tle2074 and just not connect the two NC pins.
