Subject: Best Op Amp for A Seismic Preamp ? I just purchased an OP027 to replace the OP177 hich I now use but saw no difference in the results. he baseline shifted 200mV but that compensated icely using the zero feature at pins one and eight. Can anyone say there's a better Op Amp than these o use as a Preamp ? Hi Geoff, You can type the opamp numbrs into Google and obtain free data sheets. They usually give=20 noise specifications. The LT1007 is a better=20 opamp. Regards, Chris Chapman= Subject: Best Op Amp for A Seismic Preamp ?
