LMH5401: several LMH5401 on same supply

er charti
Prodigy 10 points
Part Number: LMH5401

Tool/software:

Hello,

I plan to use 4 LMH5401 on my platform and I need to know if you have a reference design with several amplifier which share  same supplies.

I plan to have one LDO for positive supply (3.2V) and a LDO for negative supply (-1.8V). with a commode mode at 0.7V

how can I isolate each amp.? Is a ferrite bead / capacitors  are enough or should I use one LDO with amp (not cost effective).

thanks

Eric
