Hi !
I want to use LM2902 to build a LPF circuit. The schematic diagram is shown as the following. Single Supply: 5V
My question is: Whether I change the magnification or increase the amplitude of the input signal, the Vpp value of the output signal will be limited under 2.5V. The waveform will be distorted when Vpp of the output signal exceeds this value. When I try to remove C4, the circuit becomes a typical mu-circuit. But the above problems still exist.
Please help me. Thanks for your attention.
