Configuring the LMP90100 AFE's IB1& IB2 as an AC current source

Hi

Is it possible to operate the current source in the AFE as an Ac current source, by driving the VA pin (analog supply) using a external ac voltage? The main objective is to design the ac reference generator for a conductivity meter, something like a Howland current pump using the AFE's current sources.

Thanks
