UCC21750QDWEVM-025: About UCC21750 Specification (BW_AIN)

Part Number: UCC21750QDWEVM-025
Other Parts Discussed in Thread: UCC21750-Q1

Hi, 

I want to know about the meaning of the BW_AIN specification which is descripted as AIN-APWM Bandwidth in datasheet of UCC21750-Q1.

And also if there is way to test this spec.?

Best regards,

Yoonjin Kim

  • Hi Yoonjin, 

    The AIN pin's 10kHz bandwidth means that it cannot effectively pick up signal that is higher than 10kHz, so essentially it filters out some of the high frequency noises. 

    We've done some tests to show that certain signal higher than 10kHz is filtered out, you can read more about it here

    Thanks,
