Ideas for a voltmeter with ICL 7106

[meski]

Hello

I have build a voltmeter with icl 7106 "panel meter dpm 952" but i want to upgrade it and dont know how to do it. I have heard that you can with one or two additionals operating amplifiers make such circuit that the icl can measure itself power supply.

So i want to connect the voltmeter with operating amplifiers to the power supply and on the screen will show the voltage that powers the icl 7106 circuit

any one got an aidea

Don't you mean an ICL7106?
Look in its datasheet or its applications notes from Intersil and Maxim.
