Detailed Description of Software
in the Coarse Adjust drop-down list, and adjust the
Fine Adjust scrollbar to set up the output data rate.
The Coarse Adjust drop-down list and the Fine Adjust
scrollbar correspond to the output data rate coarse
adjust register and the output data rate fine adjust reg-
ister, respectively. The actual data rate is displayed in
the Actual Data Rate label.
The MAX11040 EV kit’s main window is shown in Figure
1. The Setup group box, located at the top of the win-
dow, contains Configuration, Sampling Instant
Control, and Output Data Rate Control group boxes.
Functions related to reading single-sample ADC values
in the ADC Conversion group box are located in the
middle section. Data-logging functions and data calcu-
lation are in the Data Logging group box, located at
the bottom of the main window.
To set the sample rate by entering a desired sample
rate, and letting the EV kit software calculate the clos-
est possible sample rate, use the Request Data Rate
edit box. Enter the desired data rate into the Request
Data Rate edit box and press the enter key. The pro-
gram sets up the closest possible data rate automati-
cally. The actual data rate is displayed in the Actual
Data Rate label.
Up to five devices can be cascaded by using the
daughterboards. Select the number of cascaded ICs
from the Number of Devices menu item.
Setup
All the settings in the Setup group box correspond to
the registers of the IC specified in the IC Selection
drop-down list. In the IC Selection drop-down list,
MAX11040 IC #1 and MAX11040 IC #2 represent the
ICs (U1 and U2) on the EV kit. MAX11040 IC #3,
MAX11040 IC #4, and MAX11040 IC #5 represent the
ICs on the optionally cascaded daughterboards.
To set the sample rate by letting the software detect the
input frequency, and adjust the sample rate to a
desired number of samples per cycle, use the Auto
Adjust Sample Rate group box. The software detects
the frequency of the input signal on any channel select-
ed in the drop-down list. Set up the data rate based on
how many samples per input-signal cycle was request-
ed in the Samples/Cycle edit box. The actual data rate
is displayed in the Actual Data Rate label.
When the EV kit software starts up, or when a different
IC is selected in the IC Selection drop-down list, the
Configuration, Sampling Instant Control, and Output
Data Rate Control group boxes display the content of
the IC specified in the IC Selection drop-down list.
ADC Conversion
The ADC Value Display group box, shown in the ADC
Conversion group box, displays the output data codes
and the calculated voltage values for a single sample
of all of the channels on the IC specified in the IC
Selection drop-down list. Pressing the Convert button
in the ADC Conversion group box updates the status
of the ADC Value Display group box.
Configuration
In the Configuration group box, the user can change
the value of the configuration register in the selected IC.
Each checkbox in the Configuration group box corre-
sponds to a bit in the configuration register. Click on
the checkbox to toggle each bit.
Check the Auto Convert checkbox to automatically
and repeatedly read the current ADC value at a rate set
by the Time Interval drop-down list.
Sampling Instant Control
Adjust the appropriate scrollbars in the Sampling
Instant Control group box to set the sampling instant
delay for the input channels.
Data Logging
Start Conversion
The Data Logging group box is located at the bottom
of the window. The user can select the desired number
of conversions in the Number of Samples drop-down
list. Press the Start Conversion button in the Data
Logging group box to start sampling at the rate that
was set by the Output Data Rate Control group box.
Output Data Rate Control
There are three panels in the Output Data Rate
Control group box, and each one of them has a differ-
ent way to set up the data rate of the IC. The user can
select one of them by checking the corresponding
radio button on the left of the panel.
To set the sample rate by directly controlling the ADC’s
register (coarse adjust and fine adjust), use the first
panel at the top of the Output Data Rate Control

the Save to File button, the user needs to select in the
Detailed Description of Hardware
Output File Data group box which channels will have
their sampled data saved into the file. The software
keeps a record of channel selections for each IC.
Select the IC you wish to select in the IC Selection
drop-down list, to display and allow modification of
channel selection for that IC. Press the Select All
Channels on All ICs button to check all the checkbox-
es in the Output File Data group box for all ICs. Press
the Deselect All Channels on All ICs button to clear
all the checkboxes in the Output File Data group box.
Press the Save to File button to save the data from the
selected channels into a file.
MAX11040 EV Kit
The MAX11040 EV kit board provides a proven layout
for evaluating the IC’s four-channel, simultaneous-sam-
pling ADC. The EV kit comes with two
MAX11040GUU+s installed. Eight terminal blocks are
provided on the EV kit for all AIN inputs of the on-board
ICs. Four BNC connectors are also available for the
AIN0 and AIN1 inputs of IC #1 (U1).
Up to three additional parts can be connected to the
EV kit to increase the number of input channels, by
cascading the daughterboards to the EV kit.
See the Daughterboard section for more information.
Zero-Crossing Alignment Option
In the Option group box, when the Align to Zero
Crossing Point checkbox is checked, the program
detects the rising zero-crossing point in the sampled
data of the channel specified in the IC Selection and
Channel Selection drop-down lists. When the Save to
File button is pressed, the program saves the sampled
data starting from the rising zero-crossing point.
Power Supply
Two separate power supplies are required to power up
the EV kit. Connect the analog voltage supply (from
+3V to +3.6V) to the AVDD connector, and the analog
ground to the AGND connector. Connect the digital
voltage supply (from +2.7V to AVDD) to the DVDD con-
nector, and the digital ground to the DGND connector
on the EV kit.
Evluate:MAX140
Calculation
After sampling is finished, press the Calculate button
to calculate the Frequency, RMS, MIN, MAX, and Avg
DC of the input signal of the channel specified in the IC
Selection and Channel Selection drop-down lists. The
calculation for Frequency uses a simple algorithm that
has limitations. The Frequency is calculated by mea-
suring the time between two rising zero-crossing
points. An error may show up in circumstances where
DC offset is on the order of the input-signal amplitude,
or if there is significant noise or other frequency content
in the signal that creates multiple zero crossings near
the fundamental crossing. To calculate these results for
a different channel, change the IC Selection and
Channel Selection drop-down list, and press the
Calculate button.
LEDs
There are four LED indicators (D1–D4) on the EV kit. D1
and D2 LEDs reflect the real-time logic levels on the
FAULT and OVRFLW pins, respectively. D3 and D4
LEDs latch on the fault conditions on the FAULT and
OVRFLW pins, respectively. When D3 or D4 is turned on,
press the Clear LED button in the EV kit software or
press the on-board pushbutton (S2) to turn off the LEDs
after the faults are cleared. All IC FAULT and OVERFLW
pins are open drain and respectively connected in a
wire-ORed configuration.
Daughterboard
The daughterboard comes with one MAX11040GUU+
installed. The user can cascade the daughterboard to
the EV kit to increase the number of input channels.
The software supports up to three daughterboards cas-
cading to the EV kit.
Clear LED
When any of the LEDs on the EV kit and the daughter-
board are on, press the Clear LED button to turn off the
LEDs after the overflow and the overvoltage faults are
cleared.
Four terminal blocks are provided on the daughterboard
for all AIN inputs of the on-board ICs. Four BNC connec-
tors are also available for the AIN0 and AIN1 inputs of
the IC (U1).
Sync Pulse
Press the Sync Pulse button to synchronize the output
data timing for all cascaded devices.

Cascade
Carefully connect the boards by aligning the EV kit’s
14-pin connector (J12) with the 14-pin header (J1) of
the daughterboard. Gently press them together. The
two boards should be flush against each other. If more
daughterboards need to be cascaded to the EV kit,
connect the 14-pin connector (J2) of the last daughter-
board with the 14-pin header (J1) of the additional
daughterboard.
AVDD and AGND connectors, respectively. Connect
the digital voltage supply (from +2.7V to AVDD) and the
digital ground to the DVDD and DGND connectors on
the daughterboard, respectively.
LEDs
There are four LED indicators (D1–D4) on the daughter-
board. D1 and D2 LEDs reflect the real-time logic levels
on the FAULT and the OVRFLW pins, respectively. D3
and D4 LEDs latch on the fault conditions on the FAULT
and the OVRFLW pins, respectively. When D3 or D4 is
turned on, press the Clear LED button in the EV kit soft-
ware (Figure 1) or press the on-board pushbutton (S2)
to turn off the LEDs after the faults are cleared. All IC
FAULT and OVERFLW pins are open drain and respec-
tively connected in a wired-ORed configuration.
Place the shunt on pins 2-3 of JU3 on the last daughter-
board (the one farthest away from the EV kit board),
and place the shunt on pins 1-2 of JU3 on all other
boards (including the EV kit board).
Power Supply
Two separate power supplies are required to power up
the daughterboard. Connect the analog voltage supply
(from +3V to +3.6V) and the analog ground to the
