# What limits increase of power supply voltage of operational amplifiers (op-amps)?

As title says, what limits increase of power supply voltage of operational amplifiers? Is there any significant drawback related to increase of power supply voltage other than pure energy consumption problem?

So like any slowdown of the amplifier process, size of op-amp or power supply has to be bigger, or those kinds of issues. Is there any of them happening due to power supply voltage of op-amp increasing? Anything related to transistors?

• Integrated Circuit process breakdown voltage is what limits IC opamp supply voltage. Different IC process can have higher voltage limits, but with various design tradeoffs. Most of the IC demand is for lower voltage operation, so that's usually where most IC fabrication "new-process development" efforts are directed. – MarkU Sep 8 '15 at 23:56
