OPA855: Flicker noise specification and its corner frequency

Mao Du
Prodigy 20 points

Part Number: OPA855

Hello,

I do not find the OPA855 flicker noise data and its corner frequency in the datasheet? 

Do we know how low is the flicker noise level of OPA855?

Thanks,

Mao

    Mao,

    On a part like OPA855 with GBP of 8GHz, the last thing you should care about is the 1/f noise corner and this is the reason it is not shown.   Having said that, considering the high speed of the amplifier and the fact that it's bipolar input transistors, you may safely assume 1/f corner frequency is below 100Hz.
