small quantity op-amps

vitalstates · 2nd December 2007, 01:37 PM

I've been searching in vain for 1na217 & opa137
I've found some of one at rapid and some of the other at digikey.....
but min qty of both is 500

has anybody got any idea where I can get 5 to 10 of each.....

& I can't find any equivalents for either

You can get the opa137 from RS components...

Thanks Nordic but £258 for reel of 250 is a bit strong when I only want 5...and the only alternative is the small smt version which is no good to me.....

Hi,
there must be other low noise bal to unbal opamps you can use rather than the ina217.
The opa137 spec is met by any low quality FET opamp for about 40p ($0.8)
