Hi everyone!!
i'm using arduino square pulses for human body(ElectroAcupuncture), i want to amplify those 5v to 25,30v(variable). If anyone have idea about 30v op amp or any other amplifier ic please share it. I'm using current limiter circuit after the amplification.
your help would be appreciated. Thanks

Use 3, 9volt batteries a NPN transistor driven by the Arduino.

thanks got it. I think opamp can also do this job more easily :).

Most opamps not designed for low-voltage use are rated for +/- 18V maximum,
ie 36V supply range.
