High voltage opamp (40V)

opamp 40v

I need to design a high voltage opamp with 40V supply,
We know that in low voltage opamp design we need to worry about things like input range, output swing,etc. In high voltage opamp design, what should we take care ?
Could someone recommand me some related papers or books?

Hi Alles Gute,

The very critical thing before you start your design, you should have your specification which fits into your particular application. Then you can determine the circuit structure/architecture based on the spec and so on...

However I will give you a reminder since you mentioned 40V supply. Beware of the body effect which may become worse with high voltage. Connect source to bulk to eliminate this effect if possible.

Hope it helps.
