LPV521 output swing

Hi, folks

Could you update figure 31 and 32 of datasheet?

At Figure 31, Crossing x and y represent VS=1V and VOUT=0V respectively? and also step of Y equal to 1V?

At Figure 32, Crossing x and y represent VS=1V and VOUT=2V respectively? and also step of Y equal to 1V?

Also Vo have a big process variation, typ is 2mV and Max is 50mA. Can you minimized this number?

    Hello Keiichi,

    The axis of the graph are "compressed". This is an intermittent problem we have been having with the ex-National datasheet graphs.

    Below is a snapshot of the original National graphs:

    The typical 2mV output swing is at room temperature only and is not guaranteed.

    The 50mV Max is over temperature (-40 to 125) - which would warrant a much wider range.

    Regards,

    Hello, Paul

    Thank you for your reply.
    I understand +-50mV is over all temperature range.
    In this case, could you let me know the meaning of following spec with "Temperature extremes"?
