TLV27L1: Biphasic Signal Generation Problem

Part Number: TLV27L1


I have asked my question before in this form. Now I face the problem again. I feed square waves of the Opamp for both inputs and get biphasic signal. But I don't what it is happening then I lost negative cycle of my signal. So, the output signal turns to monophasic signal. -5V and 5V supply voltages are correctly feeding the IC.

I have erased my microcontroller for not feeding any signal of the opamp. Then I replaced it but the problem is still there.

In the output figures, yellow graph is inverting input of the opamp and green is noninverting input. The third figure is output of the opamp. Do you have any idea to solve the problem?

Thank you
