AMC1305M25: Digital filter for AMC1305M25

Part Number: AMC1305M25
Other Parts Discussed in Thread: AMC1210, TMS320F280049

Hi, 

I want to use AMC1305 for high side current sensing for my buck converter, the micro i am using is F280049, which doesn't have delta sigma filter module. Datasheet recommends AMC1210 as digital filter for delta-sigma modulator, but datasheet of AMC1210 has 4 filter module and specifically for inverter.

My questions are:

1. Is there a device that has only one filter ?

2. with F280049, how to use the parallel D0-D7 data transfer?

Thanks,
