MAX11040 Evaluation Kit/Daughterboard
the Save to File button, the user needs to select in the
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.
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.
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.
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.
Sync Pulse
Press the Sync Pulse button to synchronize the output
data timing for all cascaded devices.
Detailed Description of Hardware
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.
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.
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.
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).
