Dear Colleagues,
I have to develop a circuit using ADS1282 as the analog digital converter. We have to connect a seismometer like this http://www.eentec.com/SP-400_data.htm to provide the 3 necessary differential signals to my device. If you check in the sensor specifications you can see that the output signal swing can reach +-20Vpp in the differential mode and of course this is too much for the ADS1282 inputs. In the ADS1282 manual I can see on page 42 an Geophone interface Application, Do you have any circuit interface sample for Seismometer? Should I use a simple voltage divider or another solution? (maximum symmetrical supply +-5V)
Best Regards
