Hi im using AD5410, 12 Current source DAC.

I have configured the DAC to 0-24mA output range.

I have set the value in the data register of the current source dac as 0xfff, for which i have to get an output of 24mA.  However output reading in the meter(The meter is precise & calibrated one) shows 23.92mA. The difference between 24 & 23.92 = 0.08mA. Which corresponds to 12 LSB (for 24 mA the resolution is 0.00585 = 1 LSB.)error. 

 

What could be the reasons for the this magnitude of error & how to eliminate it.
