[sdiy] Voltage References

[Matthew Smith]

Hi Folks

Any favourite methods of generating +/-10V reference voltages from a 
+/-15V supply? Looking to keep component count down.

First thing that sprang to mind was a dual opamp configured as a pair of 
buffers, fed by a pair of resistive dividers. But the first thing that 
springs to my mind invariably has some major flaw ;-)

Cheers

M
