Anybody need a whole lot of LME49740NA quad op amps?
« on: March 26, 2020, 12:26:41 PM »
I need 50 DIP-14 quads for rework, I don't want to solder SOICs to adapters, and direct coupling is neat. So LME49740NA it is.

Rochester is the only one still stocking this chip. They have a USD $250 minimum, which comes out to 158 chips. They are $1.63 $1.59 apiece at that quantity before shipping, which is a great deal considering they've been out of production for a few years. It's also lower than any current production nicely-spec'd quad that I've seen.

If I can find a handful of folks who need these as well – say, 25 minimum? I'm happy to do the buy, split it up, and send it out. Anywhere in the world if you pay shipping – USPS is usually cheapest, reinforced flat pack. PayPal is fine.

An update: the rep I spoke with implied that anything could be combined to make the minimum purchase happen, it doesn’t have to be just one item. So let me know if there’s something they have that you need!

Would these work?

Not unless there's some way to verify that they're real. I've had a recent experience with counterfeit op amps.

I would buy a good chunk of lme49710, maybe 100-150.

Hey man! Sweet. Oakland. Someone else inquired about 50, so I'll confirm with them. If so, we're almost there.

Wow I just checked out the feedback on that eBay store. Hell naw.

Looks like they only have a SOIC version in stock.
