I am trying to understand ad9144 DAC output data format. I found some equations at datasheet page 79, which explains output curretnt. As I understand from these equations, there are 2 options for DAC data output. One is binary format and the other one is two's complement format. According to two's complement format 0x8000 is most negative, 0x0000 is 0 and 0x7FFF is most positive output, right?


My actual question is, is there any equation that explains I-V convertion at the DAC output. Because I couldn't find any one of them from datasheet. By the way I am using ad9144 on DAQ2 board.
