That's a possible. Albeit shockingly expensive from Farnell.

Had a look at LME49710 from National?
1.79$ @ 1K, not in farnell yet, but probably cheaper than the 5534/2, when it first came outmartin
Anyone found any of this sort of opamp that _doesn't_ show this behaviour? i.e. low offset, low noise input gain stage that gets rolled off for stability,
2nd gain stage to get the high LF open loop gain but is very noisy so you get very bad output noise at HF. The AD8671 family do this.Regards Ian
I did indeed find it.
Sounds a bit like it. I have some coming as samples.

We pay about $5.25, so use them sparingly. OP-27 is about $1.25.
John
In what quantities ?
OP-27's always been considered nice but not that quiet by modern standards. The newish National parts look very attractive btw. They seem to be making themselves a new niche in high performance audio (with GP spinoff applications) whereas TI seem to be losing one. I'd have thought they'd do more with the BB division.
Linear's parts (as ever) just seem to be expensive.
Graham
Farnell are still £6.41 / $12.80 in 100s.
They really ought to make their volume pricing more competitive.
Graham
have you tried Dengove?

oops Dengrove

$4.95 US in 100's from Digikey, 5.75 in 25's. Similar prices from LTC,
4.75 in 1K. The 'eh' version is about 50% more.
And there are are 2 manufacturers.
The newish National parts look very

Many American companies, notably Microsoft, impose a European price penalty, usually in the 20-100% range. My company doesn't. Maybe we should reconsider...

Microsoft's paractices are quite shocking.
That kind of thing just invites piracy. Many small admins here counter by running 2 copies for every 'legal' purchased one.
Graham
Who are they ?
Graham
They are used by a friend ( I have one ) for sourcing components for medium production runs when the RS/Farnell prices get out of hand.Or getting hold of wierd mil spec stuff, old style tants etc
I'll get a contact name, if you are interested, but not for small quantities (10s or 20s)
martin
Bullshit. There are plenty of sources that only charge what we pay here. The last Co. I worked for had plants in UK, India, Germany, and China, and The UK facility preferred UK sourced parts.
If you can live with +/-5 V try MAX412

I can't.
