+-5 from single +5

Question

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?

Hi, thanks. 
 I think these are crowded and complex circuit, I have found LTC1174 can do my job it can give me -4.7 from 5v. 
 I think TI is much clearer in categorizing their power supply, specially I didn't see anything like split-rail in ADI. 
 
 But finally I've found LT1617 .Thanks for TI approached me to search among inverting. 
 This is satisfied me for this -5v but what if I wanting -3.3 or -1.8 ????update: fortunately LT1417 have bias network for setting these voltages. 
 Best regards. good luck.)
