Chapter 2
When you use the bipolar configuration, you need to select whether to write straight binary or
two's complement to the DAC. In straight binary mode, data values written to the analog output
channel range from 0 to 4,095 decimal (0 to 0FFF hex). In two's complement mode, data values
written to the the analog output channel range from -2,048 to +2,047 decimal (F800 to 07FF hex).

Straight Binary Mode

The data value written to each analog output channel is interpreted as a straight binary number
when the following jumpers are set:
Analog Output Straight Binary for Channel 0:
Analog Output Straight Binary for Channel 1:
This configuration is shown in Figure 2-18.

Two's Complement Mode (Factory Setting)

The data value written to each analog output channel is interpreted as a two's complement number
when the following jumpers are set:
Analog Output Two's Complement for Channel 0:
Analog Output Two's Complement for Channel 1:
This configuration is shown in Figure 2-19.
