LM2904B: switching noise input

Takao Yamamoto5

Part Number: LM2904B


Hi team,

Is it acceptable to be applied switching noise 1.6MHz to the input side of this amplifier?

I think to use this device at output line of LED driver. I case about voltage tolerance, but the switching noise cannot be removed.

Best regards,

Yamamoto

    Hello Yamamoto-san,

    Yes, that frequency can be applied. The response may or may not be as desired. 

    What characteristic of 'output line of LED driver' would you like the LM2904B have as an output?

    More details about the input waveform and desired output would help me formulate a more specific answer.
