OPA2191: OPA2191 circuit Condition

Part Number: OPA2191


I would like you to confirm condtion about figure 46 and 47.

There is only "Overdrive = 100mV" about ciucuit conditon. So I would like you to confirm circuit condition.

Could you please confrim ?

Best Regards,

  • Hello Ryuuichi,

    Figures 46 and 47 depict the OPA2191 performance when the amp is employed as a compator. Like conventional comparators, a step input having a certain level of overdrive is used for the propagation delay time tests. I verified with our Test Engineering that 100 mVpk (200 mVp-p) was the level used for the OPA2191 propagation delay time graphs shown in the datasheet.
