Armstrod, where can I buy 637 opamps?
Jolida JD9 Opamps
I've been following all the info about different opamps available for this unit and after awhile it all becomes a bit confusing. I've had my JD9 for a year now and I'm quite pleased with it but would also like to improve it if possible. I'm not handy with a soldering iron so changing the opamps would seem to be the route for me. I'm using a Denon DL-304 LOMC with very low output (.18mv) so I would like to keep the noise floor as low as possible. Could someone give me guidance as to which opamps would be best to use in my setup? Or should I just leave it be and enjoy it as is?
Regards, Sam

I got mine as samples directly from TI, but here's one place to buy them at retail: http://parts.digikey.com/1/parts/464939-ic-opamp-gp-80mhz-sgl-hs-8-dip-opa637bp.html There are many others; just Google "OPA637BP". David |
There is a cheaper version of the 627/637 family you may wish to try. It is the 827. Very close to the 627/637 in specs, a bit better noise and a bit better distortion, and cheaper. It is only available as surface mount mount though, so you have to use a Brown Dog adapter or similar if you need an 8 pin DIP. BTW, its about $7.50 in singles. If you want to buy one pre-mounted, Brown Dog has the 827 for $22 mounted. The 627/637 DIP has gone up to between $25 and $35, depending on grade. |
