AD8226 filter circuit

Hi

I was referring to MT-070 to ad filter circuit to AD8226.

...

IOUT_ AD5420 and IOUT_ AD5420_R are two terminal of resistor in a 4-20mA current loop where I'm sensing. As HART signals also flows through my 4-20mA loop, Is there any dependency while selecting filter to this instumentation amplifier with respect to frequency. HART signals at loop(FSK signal) will be at frequency 1.2KHz and 2.2KHz. Please help me out.

Regards
