small dc signal amplifier schematic need

[phoenix_1]

I will probe with LM358 and LM324.
Also with inverted amplifier version.
Apropos I use PicMicro 10bit ADC.

Hi Robert,
The LM324 or LM358 can be used, but remember, they are not rail-to-rail, you have to design the circuit accordingly. Freescale Semiconductors has some very interesting "Application Notes": AN 1517 and AN 1325

there are many more on their web site. You might want to study those.
If you want to use a 10bit ADC I would suggest using it with a 2.048V reference voltage to get a decent resolution.

Thank's to all and you Misterg it was help 100%.
AN1517 and AN 1325 was final and the best help.
At these moment all is in test mode.

Regards and thank's again to all.
