• RE: Should noise bandwidth be equal to signal bandwidth in noise calculation?

  

  Liang Huang

  Resolved

  Hi Marek, Thanks for your detailed reply. So high GBW is not always better right? If my signal bandwidth is 10kHz, it would be better to use a lower GBW opamp (OPA182, for example) instead of OPA627?
