AD5293 VDD/VSS decoupling capacitances

I need some advice about decoupling capacitances. Data sheet says VDD and VSS should be decoupled with 0.1uF and 10uF capacitors. The problem is I have around 150 digipots in the design so capacitors, especially the 10uFs, will demand a lot in terms of bord real state and power supply.


What do you suggest? One 10uF for each line, one every N digipots?
