stm32f303 opamp precision

Question asked by tag.aseok on Jan 14, 2017


It is mentioned in the stm32f303vc that it's opamp GBW is 8, but as i measured in the lab, the opamp output (i tested opamp 1&2 in follower mode) can't follow a sine wave above 700KHz in frequency, i.e output becomes like triangle wave and above 3MHz, it's amplitude will be filtered also.
