    Hi there,
    
 
    I have a quesion about AD8691.
    
 
    http://www.analog.com/static/imported-files/data_sheets/AD8691_8692_8694.pdf
    
 

    Looking at the input voltage range of the datasheet, it says +3.9V(Max) at Vs=5V.
    
 
    And also this is  specifired at　T A  = 25°C.
    
 
    I need information on input voltage range when Ta is  between -10℃ and +50℃.
    
 
     Do you have the data on that? 
    
 
    Over the temparete, how much do you think input max range would change?
    
 
    Thanks in advance.
    
 
    Best regards,
    
 
    Tarzan

      Hi Tarzan,
      
 
      I just confirmed from the application engineer that the IVR max at -10 degree C would be about 3.7V. At +50 degree C the max IVR will typically increase less than 1V. It is just an estimate and is not guaranteed. It is recommended that you should not exceed the guaranteed limit of 3.9V max IVR.
      
 
      Hope it helps.
