Iout – AnalogThe Iout terminal, the terminal on the right
side of the symbol, is the connection to the
DAC.s current source/sink.
It can be routed to any analog-compatible
pin on the device.
When the highest current range is selected
(2040 µA) the output should only be routed to a
specific set of pins that provide a direct low
resistive path. These port pins are P0[6], P0[7],
P3[0], or P3[1].

ipolarity – Input*The ipolarity input is an optional signal input pin.
This pin can be controlled by Digital components or
control register. This is used to control the direction of the
current, either source or sink to its load.
When this pin is connected to logic .0. (source), the
output of the DAC sources current to a load that is
connected to VSS or other voltage that is at least 1.0 V
below VDDA.
If the pin is connected to logic .1. (sink), it supplies
current to a load that is connected to VDD or other
voltage at least 1.0 V above VSS.

Follow the below steps to do this:• The Lab already has the LCD Character
component installed and configured.
• Add a IDAC8 component from the
component catalog.
• In the general tab, configure the
IDAC8 component as in the image
