       Hi. I have the above scheme using the AD8054 op amp. If I ground the JP2 pins I have 0.15 V at the 1, 2 and 3 pins. When I raised pin 3 in the air and connected it directly to GND I still had 0.15V at 1 and 2 pins. If it is not clear in the picture, 2 and 3 pins are inputs and 1 is output. Supply is +/- 5V. What ever voltage there is at JP2 pins there is always an 0.15V extra voltage at the output. Could anyone please help me? Thank you.
