    Hi
    You can try with folded cascode opamp. It will give you a better specification.

    Yes as "@Analog_Domain" mentioned, you can use folded cascode op-amp but if swing is not a issue and you want to dissipate very less power (power dissipation is your concerned) then go for telescopic cascode .

    For high gain you can also use gain boosting in your op-amp with common mode feedback to insure your constant output voltage.
