Detailed Description of Hardware
MAX11600–MAX11617 EV System
The MAX11600–MAX11617 EV system is a complete
data-acquisition system that consists of one master
board and one of the six companion EV kit daughter
boards.
MAX116XX I2C Master Board
The MAX116XX I2C master board connects to a PC USB
port and allows the transfer of I²C commands to the EV
kit daughter board.
Power Supply
One +5.5V power supply is required to power up the
MAX116XX I2C master board. Connect the positive
terminal of the power supply to the DVDD connector
and the negative terminal to the DGND connector on the
master board.
EV Kit Daughter Boards
The EV kit daughter boards are fully assembled and
tested PCBs that demonstrate the capabilities of the
MAX11600–MAX11617 4-/8-/12-channel, 8-/10-/12-bit,
3V/5V, low-power, high-speed I²C ADCs with internal
reference.
Each EV kit daughter board evaluates three different
ADCs. See the Ordering Information/Selector Guide
section to select the desired EV kit daughter board and
ADC.
Carefully connect the EV kit daughter board to the
master board by aligning the EV kit daughter board’s
20-pin connector (J1) with the 20-pin header (J1) of the
master board. Gently press them together.
Voltage Reference
An on-board +2.5V voltage reference (U3) is provided
on the EV kit daughter board. To use a user-supplied
reference voltage, see the applicable EV kit daughter
board’s jumper table to place the shunt of jumper JU3
to the appropriate position and connect the external
reference voltage to the REF connector.
Power Supply
By default, the EV kit daughter board is powered from
the master board. To use an external power supply,
move the shunt of jumper JU4 to the 2-3 position.
Apply a user-supplied power supply at the AVDD_EXT
connector.
User-Supplied I²C Interface
To use the EV kit daughter board with a user-supplied
I²C interface, first move the shunts of jumpers JU1and
JU2 to the 2-3 position and connect the user-supplied
SCL and SDA signals to the corresponding SCL and
SDA connectors on the EV kit daughter board.
