LM224: Output Sourcing Characteristics

Katsuhiko Kaizawa
Intellectual 2045 points
Part Number: LM224


Hello support team,

Let me ask about the Output Sourcing Characteristics in the LMx24 datasheet.
www.tij.co.jp/.../lm324.pdf

The figure-1 shows Output Sinking Characteristics with different VCC (5V,15V,30V), but the figure-2 shows Output Sourcing Characteristics with only VCC=15V.
Could you provide the Output Sourcing Characteristics data with different VCC?
If the Output Sourcing Characteristics does not have any VCC dependency, please explain the reason.

Thank you and best regards,
Kaizawa

    Katsuhiko-san,

    Output souring is independent of VCC because the regulation loop (in green box) is independent of VCC and GND and the ~100uA current source.

    As you may expect, there is a temperature dependence. VOH gets a little closer to VCC at high temperature and short current drops a little.
