HI,
Do all ICs need voltage regulation? More to my concern, do high precision op amps, instrumentation amps, need regulated power supplies?
At the moment I am using an INA118, a dual supply inst-Amp, I am using a 9V battery with a precision virtual ground IC TL246, to split the voltage to get +-4.5V.
If I need regualted voltage, then I plan to use an LM317 to get a regulated 6 V and split it to 3V. (I believe getting more than 6V out of an LM317 with a 9V battery will not give reliable voltages over time)
I'd prefer if I didnt need a regualted voltage, but not sure if I do?
THanks
