The typical supply current on the ADL5902 is specifed as 73 mA and 90 mA at 25 degC and 125 degC respectively. What is the worst case value?





The attached plot gives a sense for the part-to-part variation in supply current.


These numbers do not exactly line up with the data sheet typicals for 25 degC or 125 degC. The sample here is a smaller population of devices compared to that used for during full device characterization.   As a guideline, if you are planning to use the device up 125 degC, I would suggest budgeting for at least 100 mA  for the ADL5902.
