Configuring the 7805ALP for Twos Complement Coding
Figure 23 shows a typical configuration for the 7805ALP. The circuit can be used for either 3.3 V or 5 V operation and
uses the internal VDD/2 as the reference for the part and 10-bit parallel interfacing is used. The following are the steps
required to operate the Main DACs in this part.

System Control Register Write:
MODE = 0, address inputs (A2, A1, A0) are don’t cares.
Write 020 Hex
Configure part for 10-bit parallel, twos complement coding, normal operation Channel
Control Register Write:
MODE = 0, address inputs (A2, A1, A0) select desired channel.
Write 011 Hex
Internal VDD/2 selected as VBIAS for DAC, and any DAC data writes that follow are to
the Main DAC.
