hi again
In fact I've posted for the INA114 but It was for the design of the current generator
I never succeed to have a enough good stability of the 30 UA current source depending of the load

Sinoj,
The LMC6062 can operate from +/-5V supplies. What matters is the total voltage between the supply terminals.
See this blog for some clarity on the issue...
