Part Number: TIPD122 I have fabricated a 0.1Hz to 10Hz noise filter based on reference design TIPD122 for μV amplifier circuit testing. I am have problems with noise in the high-pass filter stage limiting the over device performance. When jumper JP7 is…

Hi Tim,
The .txt file you provided is exactly what I'm looking for. FYI, the gerber files available for download for TIPD122 ( tidc166.zip), includes a .DRL file that has an issue.
Thanks very much,
Mark
Ron's circuit will work well. If the noise is lower you may consider this reference design which describes how to measure the 0.1-10Hz noise in roughly the same way we do during device validation.
