I am attempting to convert a single ended signal (0-5V) to a differential signal (+/- 5V about 0V) using an AD8131ARZ. I have it wired as per the attached schematic. When I supply +5V to the positive input DIN+ of the AD8131, the output behaves correctly with +/- 5V. However, if I ground the DIN+ input the outputs hold at or near 0V instead of inverting. So, it halfway works.
Experimenting, if I disconnect DIN- from ground and apply a voltage slightly more positive than zero to it while grounding DIN+ I begin to get the desired effect of the signals inverting. However, the amplitude is not correct. The amplitude appears to be the difference only (gain of 1).
How can I achieve my stated goal with this IC?
