I_mon accuracy of LT3089

Hello guys,


I am using the LT3089 for regulating the voltage and measuring the output current I_out simultanousely. The monitor current I_mon should be 1/5000 of I_out.


There are neither details about the accuracy nor the drift of I_mon.


My measurements showed that I_mon is about 5 % to 10 % higher than 1/5000 of I_out.


Is it still within the specifications or is there way to compensate this effect for higher monitor accuracy?


Best regards
