AD817 Reduced Output

Im using a op amp as the front end for my data acquisition card

Choose the AD817 amp powered with a 12v single power supply

I have a 4v peak to peak signal going into my system

The signal im getting on the output of the AD817 seems to be just the positive 2v peak

Don't seem to be getting the lower 2v part of the signal

    Hi Bigshop,

    You may try to connect AD817 with positive and negative supply if you have input that will swing to positive and negative range. The op amp input and output should be keep within the supply rails to function properly. You should also consider the Input voltage range and output swing specified in the datasheet to make sure the op amp works well with your application.
