Lee,
You are correct. The red text on figure 3 is labeled incorrectly. The term HPF and LPF are swapped. The first stage is a HPF, and the next two stages are LPF.
Regarding using the circuit for a 5V supply:
The easiest thing to do would be to use …
Hi Lhagva,
For the Geophone application, you could use and benefit from the following precision ratiometric resistors.

Hi Dieter,
The INA126 is still active and available on ti.com, please see the product page to view the current status on the device: INA126 data sheet, product information and support | TI.com
Both the INA126 and INA826 cannot operate at a VCM=0V with…
Hey Mike,
There is one potential non-idealistic aspect of shunt layout: there is curvature in the expected current density across the shunt. So most current will want to take shortest path around this curve which could result in significant gain (shunt…
Hi Francis,
What frequency range are you looking for here? We have devices with integrated EMI filters, where the filter cutoff frequency is > 100 MHz, but my interpretation of this post is that is not what you are looking for.
For lower frequency…
