Hello
I am using OPA 552 PA as a comparator ic for generating PWM signal for gate driver FOD 3184. I connected triangular carrier signal to inverting input and DC reference signal to non inverting input. Vcc to pin 7 and ground to pin 4. but i am getting a pulse with 1.20 V offset, and when i connect this output to the input of the FOD the voltage level of output of opamp reduced. how to remove this offset.
hello
If you look at output pulse, the lower voltage value is 1.2 V instead pin 4 (Vcc-) is connected to ground. I want to drive the gate driver FOD 3184 for generating switching pulse of 100 KHz. It needs lower voltage value should be zero. Give me some solution. I choose this opamp ic for generating 100 kHz frequency pulse.
hello sir
I removed the offset by supplying negative supply with different source shown in CH3. I connected this pulsating signal to the FOD 3184 gate driver. but the output of gate driver is amplified but width is distorted, I dont know how. please help.
