Hi,

I recommend the AD8129/AD8130 amplifiers for the box marked ???.

Take a look at the AD830 data sheet (the AD830 was an earlier part with the same architecture as the AD8129/AD8130) -- it has a bit more theory.

Don't forget:

1. Check the slew…

Hello Frank,

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…

Hi, Andy.

Differential amplifiers, like AD8138, can't be used to add two differential signals. They are called differential amps not only due to their input configuration but also by its output voltage which is the "difference" between the two different…
