Nearly any opamp will work with a +5V and -5V supply. The LM358 is dual, not single, and is pretty slow if speed doesn't matter.kimmi said:is Lm358 ok for this + 5v - 5v
You won't find a schematic, this is your project.can i finde a schematic for this here on forum

I have a problem need to make this to work on adc input
my volt is (minus)-10mv to +65mv to smale to feed the adc what to do & howto do it

The pot is to adjust the zero to cancel the opamp's built-in offset voltage. Your opamp might need the opposite voltage and more offset adjustment for your circuit.kimmi said:If I use a 741 and add a pot 10k to pin 1 and 5 and to -10v is that not same at zero adj. ?
