Thread Summary

                The user seeks to determine the current draw of 12 AD202KNs from a +15V power supply. The datasheet specifies a no-load current consumption of 5mA for the AD202K. To estimate the total current, calculate the load current for each AD202 and sum it with the no-load current, treating this as a minimum value.

I'm looking to properly size my power supply. I am hoping to run 12 AD202KNs off of a single power supply. I see in the data sheets the AD-246 requirements but I wasn't clear on whether they applied to AD202s from a +15 V source. 

 


 
How much current should I expect a single AD202 to draw while loaded? How do they sum for multiple AD202s?

 


 
Thank you!
