High Pass Filters for AD620 and AD820

I have a circuit using AD620 and AD820 opamps, and am trying to figure out the simplest way to integrate a high pass AND a lowpass filter.


The context of each component within the circuit currently matches these examples...

I've found examples and explanations online and in the data sheets explaining how to create low pass filters, but cannot find anything about high pass filters.


To create a high pass filter, would it be as simple as flipping the resistors and capacitors?  Does anyone know of documentation describing how to integrate high pass filters around these components?
