LMH13000: MINVIout Clarification

Part Number: LMH13000

Hi,

What is the difference between MINVIOUT Specification shown in Section 5.5 of the datasheet (pg. 5) and Figure 5-27 (pg. 12). Why is the two data shows different MINVIOUT for the similar IOUT value?

Which one to use as reference for my design?

Best regards,

    Hi Andi,

    In the electrical table Section 5.5 of the datasheet (pg. 5) is the MINVIOUT across temperature (-40 to 125C) where as in the Figure 5-27 (pg. 12) it is plotted for room temp.

    Regards

    Hi Anant, 

    I am a bit confused. Isn't room temp. (25C) within the -40 to 125C?

    Regards,
    Andi

    Let me rephrase in the electrical table we are promising / testing the part to ensure it has linear IOUT capability and hence has the minimum value. We also guarantee that even if temp goes from -40 to 125 and if you have maintained this Min Viout we will ensure our current source is not crunched.

    The fig shows the min headroom for a device which is selected randomly ( this makes this data typical ) and it shows the min headroom for room temperature.

    Based on the the device operation temperature please choose a min VIOUT accordingly.

    hope this helps.
