The DAC12 supports both straight binary and 2s compliment data formats. When using the straight binary data format, the full-scale output value is 0FFFh in 12-bit mode (0FFh in 8-bit mode). For the 2s compliment data format, the range is shifted such that a DAC12_xDAT value of 0800h (0080h in 8-bit mode) results in a zero output voltage, 0000h is the mid-scale output voltage, and 07FFh (007Fh for 8-bit mode) is the full-scale voltage output.
