It's all in the data sheet. Vout versus Vsupply versus load. Bunch of graphs...

What I find interesting about the new part is the relatively low bias current compared to something like an NE5532. Thiswill make it easier to do a low noise design with a high inductance MM cartridge without having to resort to using a JFET-input device.

Just for the record, Bob Pease is a wonderful guy, but he is quite hard of hearing. He only hears in one ear.

I hate to admit this, but I've been sitting on some LM4562's for some months now. Just no time.

I have a few to stick in my UcD amp, and maybe to try in a preamp.

Mike

Having talked with a few of the NSC folks in recent months, it has got to be a pretty exciting place for "ana-loggers"

I guess National will develop a new family including fully differentials for modems and other stuff, and this is just the first sibling. They already have the low voltage possibility.

I needed 4 AD797's for a project so bought 200 of them from Future -- and only have 6 left.

Hi Jack,

Is there some hidden logic at work here?

Before DK became a distributor in the U.S. I bought my ADI chips from Future or Newark -- could only purchase 200 at one point -- I made more boards than I expected and parted out the rest to other DIYrs and a physicist friend. I did the same thing with AD825's.

The LM4562 certainly appears to be priced right --

Hi Jack,

I missed that pricing, what is it?
