Ive been trying to locate a suitable unity gain buffer amplifier
IC that can drive a 50 load.
Application is to buffer a VCO output at 5Mhz.
Needs to be 8pin DIP

LTC's LT1206 comes in TO220, miniDIP and soic packages,

and operate on a single-ended supply.

Oops, +/-5V supply. What's your signal voltage? And did

Maybe an LT1191?
