Comparator Output with HIP4080

smartsabby · 13th March 2008, 02:51 AM

Hello guys,
Im using the HIP4080 as the gate driver for my class D audio amplifier design. It also has an input comparator and so I guess I should not have to use an external op-amp to generate the PWM switching signal.. I have connected the circuit as given in the application note of HIP4080. I am not able to see any square pulse at the output of the comparator...
Please let me know how can see the output of the comparator on OCR?

Thanx a lot...
