What would you recommend?-----
I am in need of a Low noise differential input/ single ended output amp to cover approx 100 KHZ thru 10 MHZ (a higher shelf freq. is ok). The driving source will be Shielded, Single Turn LOOP Antenna. Input balance is important. Noise figure of the amp is extremely important. The gain needs to be no more than 20 DBv (x10).
Take a look at the AD8129. This is a receiver for signals over twisted pair cables. It is a differential input single ended output amplifier with sufficient bandwidth for your application at Gain=10.
You can also look at the AD830. This part might be just short of your 10 MHz BW requirement at Gain=10.
