AD5413 BLOCK DIAGRAM AND FUNCTIONS
The EVAL-AD5413SDZ plugin is organized to appear similar to
the block diagram shown in the
AD5413 data sheet. This graphical
user interface (GUI) correlates the functions of the EVAL-
AD5413SDZ with the descriptions in the
AD5413 data sheet.
Full descriptions of each block and register setting are available
in the
AD5413 data sheet. The full screen AD5413 block
diagram with labels is shown in Figure 8. Table 3 and Table 4
describe the functionality of each block.

the hardware. If either check box is selected, this represents a high state. If either box is not selected, this represents a low
state.
G
If the /RESET check box is selected, the SDP-S board sets the RESET pin high. Otherwise, the SDP-S board pulls the RESET pin low.
H If the /LDAC check box is selected, the SDP-S board sets the LDAC pin high. Otherwise, the SDP-S board pulls the LDAC pin low.
I The EVAL-AD5413SDZ plugin monitors the FAULT pin. If the FAULT pin is low, the /FAULT indicator LED lights up red.
J VI_OUT displays the calculated output at VI
OUT
, and displays if the output is in voltage, milliamps, or is high impedance (high-Z).
