I assembled the circuit that was referring to the Figure5 in the AN-934 in order to make the operation test of the AD8336.
In order to operate the AD8336 by itself, we have entered a 250mVp-p sine wave.
When I set GNEG=0.75V and GPOS=1.5V, output signal became square wave of ±5Vpp.
Could you please tell me what to do in order to make the output signal to 250mV of the sine wave?

Circuit structure and resistance value are same as the Figure5 in the AN-934.
I am supplying the voltage directly to the GPOS and GNEG without AD736, AD8551 and ADP3339.
Please advice me about this issue.
Thanks.
