Hi ,


The Digital Input data range  to any channel data-register of DAC IC AD5755BCPZ is ( 0x0000 to 0xFFFF )i.e ( 0 to 65535 in decimal )


Now if in case any positive offset output  ( Voltage or current ) is coming for zero digital input( 0x0000 ) then how can that be corrected i.e how can we   remove  positve offset error and get ( 0V or 0amp )  for zero digital input data ?


Is it that we have to use offset register ( as mentioned in the datasheet ) to remove any positive or negative offset error  ? if yes then please explain how  ?


Thanks & Regards !!
