Re: [linrad] A simple front end

Hi, All !

Another option for low distortion OP amp
is OPA134/2134/4134.  

The datasheet says it has -98 dB IMD3 and 8nV/root(Hz),
note that is has FETs on input and provides that noise 
density at much higher source resistance than AD797.
I use both of them in my DSP transceiver design and
I am pleased with their performance.

All the best !
