MAX7325 Evaluation Kit/Evaluation System
Detailed Description of Hardware
The MAX7325 has eight push-pull outputs and eight
open-drain I/Os. The MAX7325 EV kit board provides a
proven layout for evaluating the MAX7325. The EV kit
comes with a MAX7325ATG+ installed.
Hardware-Reset Control
The hardware-reset function is controlled by jumper
JU3, as shown in Table 2. Putting a shunt in the 1-2
position resets all registers and puts the device in the
power-on-reset state.
Power Supplies
The MAX7325 EV kit can either be powered from the
CMAXQUSB (2.5V, 3.3V, and 5V) or from a user-
supplied 1.71V to 5.5V power supply connecting to
VDD, as shown in Table 3.
If a user-supplied power supply is used, ensure that the
voltage setting is compatible with the CMAXQUSB JU1
setting.

I 2 C Address Configuration
The combination of shunt positions of jumpers JU1 and
JU2 determine the I 2 C slave address of the MAX7325
EV kit. See Table 1 to select the appropriate setting.
User-Supplied I 2 C Interface
To use the MAX7325 EV kit with a user-supplied I 2 C
interface, install a shunt on jumper JU4’s 1-2 position.
Connect SDA, SCL, and GND lines from the user-
supplied I 2 C interface to the SDA, SCL, and GND pads
on the MAX7325 EV kit. Apply a 1.71V to 5.5V power
supply to the VDD pad of the MAX7325 EV kit.
Depending on the configuration of the user-supplied
I 2 C interface, it may be necessary to install I 2 C pullup
resistors, R10 and R11.
