Part Number: OPA355

OPA355 datasheet mentioned GBW = 200MHz at G=10 but as per graph in page13 Gain at 10v/v is ~ 15MHz can u explain me where i am wrong image.png

    Sruthi,

    As per datasheet the GBW at G=10 is around 200Mhz, that corrosponds to -3dB bandwidth of around 20Mhz.

    This is similar to the datasheet plot of gain vs frequency plot (Figure 18). Gain of 10V/v corrosponse to 20dB. Here in the plot also the gain is 3dB below the set gain of 20dB (or 10V/V) at 20Mhz.

    Regards

    Anant
