+-5 from single +5

can you suggest any way to produce +-5 from +5.
I need it for one 4ch differential signal summer op-amp plus salen-key filter op-amp.

Is there any DC/DC converter or something in ADI that doing this?

  • I'm sorry more because of bad explanation, and thanks, although ADP5075 need two more component but is cheaper, and I think it's design is slightly harder.

    But if there was comparison for their voltage flatness and noise creation performance, max current on switching, that would be good measuring stick for us.

    I couldn't find these two ADP5075 and LT6167 in first look, maybe it was my first try, but good company will also care about beginners.

    Can you tell me about their architecture differences?
