An ADC scan measures all enabled cell inputs, all
enabled auxiliary inputs, and the self-diagnostics
channel (if enabled). The conversion begins once the
STROBE bit in the ADCCFG register is set. The following
procedure outlines the steps to set up and initiate single
or continuous ADC scanning.
Set_Up:
1) Enable the cells to measure:
Note: The cell channels can also be enabled with the
checkboxes on the Voltage_Measurements tab.
2) Select the cell registers to read:
3) Enable the self-diagnostics and auxiliary inputs to

Initiate_a_Single_ADC_Scan:
1) Check the SCAN checkbox on the Enables tab, then
2) Select the Voltage_ Measurements tab and press
Note: The STROBE bit is automatically set before a read
is done on the Voltage_Measurements tab.
Initiate_Continuous_ADC_Scanning:
1) Select the Read/Scan tab.
2) Enter the time delay between ADC scans into the
3) Check the Enable_ADC_scanning checkbox.
Note: To save the data during a continuous ADC scan,
perform the steps from the Log Scanned Data section in
place of these steps.

ADC Scan
MAX11068 Evaluation System
The EV kit software allows the data, measured during
continuous ADC scanning, to be saved to file. This fea-
ture is available by selecting the File_ |_ Log_ Scan_ Data
menu item and should be set up before scanning is start-
ed. The steps below explain how to set up data logging:
1) Perform steps 1–4 in the ADC Scan section.
2) Select the File_|_Log_Scan_Data_menu_item or press
3) Enter the number (n) of ADC scans to record, and
4) Select the Read/Scan tab.
5) Enter the time delay between ADC scans into the

At the completion of this process, data logging is dis-
abled, but the continuous ADC scanning continues until
the Enable_ADC_Scanning checkbox is unchecked. The
file generated by the software logs the measured data of
the enabled channels for all the devices in the SMBus
ladder.
