 Improve Instrument Amplifier Performance with X2Y® Optimized Input Filter
By Wm. P. (Bill) Klein, PE

Abstract: The common-mode rejection ability of an instrumentation amplifier degrades with increasing frequency often resulting in a major portion of the “advertised” bandwidth becoming unusable due to common-mode noise errors. An optimally designed passive input stage filter can provide significant improvement in AC common-mode rejection. Calculation of correct component values and selection of appropriate capacitors holds the key to the solution. More...
