[rtl] how to amplify the signal from the detector?

["ahgu" <ahgu@yahoo.com>]

Wonder if anyone encountered the signal amplification problem. My detector
give out slow-varying DC signal in couple mV range. My A/D board reads 0-5V
and I need all the 16bit resolution. Where would I get a DC amplifier to
solve this problem?  Please give me some insight on this problem.

  Thanks
Andrew
