    Hi , 
    

    

    Could you please let me know if you have any information  on Output Saturation Voltage vs Load Current  (Output High）when Opamp  is using 10V - GND . 
    

    we would like to know this information as we would like to source around  20mA in to load .
    

    Or if you have Source current information for 10V -GND operation .
    

    

    Thanking you 
    

    With best regards and wishes

      Hi Kabekami:  unfortunately we do not have data at Vs=10V, but only at Vs=5V/3V and Vs=+/-15V.    You can see on 5V, we do guarantee Isc of 20mA minimum, and we also guarantee output swing with a 20mA load  (at 25C).   On +/-15V, these numbers rise to 35mA Isc and a output swing load test at 25mA.
      

      So the 10V supply will get you some margin on the 20mA minimum which is guaranteed at 5V.  If you want a firmer guarantee, say over temperature (which has an 18mA guarantee on 5V), then I suggest adding a pullup resistor to provide a little extra current.
