I need a replacement for this device in an 8pin dip package. Does
anyone have an extra
they want to sell or barter? These a unity gain, Jfet, buffers. Mine
is being used in a sample
and hold circuit that bit the dust. I'm trying to not have to kludge a fix.

Thanks
Jim

If I think of, I'll bring a couple home monday. I'm sure we have spares
since we have boards that use them.

It looks like (you better check if you use this idea) that an TL071
(jfet inputs) would slot in very well if you can live with the reduced
bandwidth (3MHz vs 20MHz) and slew rate (13V/uS vs 40V/us)

Unicorn Electronics has the LM310N in stock at
http://www.unicornelectronics.com/IC/LINEAR.html. They have a $25.00
minimum, but they ship quickly. Have ordered many times from Unicorn with
excellent service.
Consolidated also lists them as being in stock at
http://www.ceitron.com/semi/semi.phtml?part=LM310. They have a $25.00
minimum as well.

** Better take a look at a data sheet.

The LM310 is not jfet.
