ADA4940-1 for differential active bandpass filter at 400 kHz.

I am using a pair of ADA4940-1 to design a differential active bandpass filter at 400 kHz. The Akerberg Mossberg topology looks the most promising. (See TI's app note SLOA064, figure 11, attached). Does this make sense or is there a better way or better part to do this? I know I could use the -2 version with both amps, but I already have the -1 in stock.

 

Thanks,


George
