Preliminary Technical Data
VX pins
There are four possible inputs to the VX pins:-

Figure 70. VX5 Test point input
The software calculator shown in Figure 70 is launched by pressing
the <Launch potential divide calculator > button. The calculator
allows the operator to input the voltages that are to be applied and
then they can use the calculator to determine which resistors to use
for the potential divide.
Figure 71. VX5 Test point input calculator
An analog input:- The user can select any of the
following voltages- 0.6V, 0.75V, 0.9V, 1.0V, 1.2V, 1.5V,
1.8V, 2.0V. 2.0V is the maximum on these pins since there
is no input attenuation. The 2.0V is the Full scale value of
the reference of the ADM106x’s ADC.
A digital input:- Once selected in this mode, the user can
drive a high or low (1 or 0) simply by clicking on the
button provided.
An oscillator input:- This feature is only available on
VX1 input and allows the user to input an oscillator from
1Hz to 1000Hz +/- 2.5% in thirteen predefined steps.
A test point input:- The user may wish to apply their
own external source (analog or digital) to a VX pin. Note
that this would have to follow the same constraints as the
on- board inputs (ie) the voltage seen at the pin can be no
greater than 2.0V. The user is able to apply a negative
voltage to the VX inputs provided a resistor divide is used
to bring the negative voltage into a positive range. This
input is provided at VX5 and the user is able to add
external resistors using the place holders provided. The
location of these resistors on the Evaluation board is at the
lower edge and are labeled R113, R60 and R59. In
addition to this hardware facility there is also a software
calculator provided.

VPn pins
There are two possible inputs to the VPn pins:-
VH pin
There are two possible inputs to the VH
Note- the evaluation board software window imports the names
from the pin names window for ease of reference.
Configuring the eval board ADC for reading PDO
outputs
The ADM106x evaluation board provides a 12 channel ADC
for measuring the voltage on the PDO outputs. This enables
Figure 73.
If the user enters any resistor or voltage values which cause
the expected output voltage to be out of range a warning
prompt will appear as shown in figure 72

An analog input. The user can select any of the
following voltages- 0.6V, 0.75V, 0.9V, 1.0V, 1.2V,
1.5V, 1.8V, 2.5V, 3.3V, 5.0V
The source of an on- board FET. This is to simulate a
FET based sequence, where typically, it is the source
side voltage that the user is interested in sequencing
on.
An analog input. The user can select any of the
following voltages- 0.6V, 0.75V, 0.9V, 1.0V, 1.2V,
1.5V, 1.8V, 2.5V, 3.3V and 5V Note, this analog input
is the same as the one driving VP4. The software
indicates this.
A fixed 12V- A non- adjustable 12V is provided to
demonstrate the 12V capability of this pin.
