Post by thread:[BUY]: Help, anyone got some OPA547T pwr opamps?

Hi, I've designed a board for a customer, using Burr Brown's OPA547T (or OPA548T) and am now embarrassed to find that the power opamps have become unavailable. The leadtime is apparently 16 weeks. Anybody spare a few?

Sorry I can't help, but this DOES remind me of a problem. We've got the LT1491 designed into a product. It's max supply voltage is 44V (rail to rail). They are hard to get and expensive. Anyone know of any other rail to rail quad op-amp that can handle this power supply voltage or higher? The pinout needs to be the same as an LM324.

Thanks! We tried that one... Bias current was too high. Any others?
