HI Everybudy

i am using ADC haveing differential input.
for signal conditioning i need to design a differential input differential out analogue output active fileter. can anybody help me. or give me guideline. i am stuck. thanks
 

In case you have decided to go for active filters with 60dB diff. and 65dB common mode rej. you can go in for PICOR. QPI-5LZ depending on the input threshold noise levels ...may like to for HOME | PICOR and study the proper filter .
 

Try this link:

**broken link removed**
 

This is a differential mode instrumentation OP amp .However , the common/differential mode rejection is only 40dB dependent on the OPamp matching .
Is there a DC voltage on which the noise overrides ?
