Evaluates: MAX11300
MAX11300PMB1 Peripheral Module
Default Jumper Setting
Verify that all jumpers are in their default positions, as
follows:
1) Jumper VDDIO: Connect from VDDIO to +12V
2) Jumper VSSIO: Connect from VSSIO to GND
3) Jumpers EXT_TEMP1 and EXT_TEMP2: Open
Power Supplies
The Pmod contains the MAX8752 step-up DC-DC con-
verter (U3), which upconverts the +3.3V power supply from
the Pmod X1 connector to +13V. The MAX5084 (U2) linear
regulator then regulates the +13V input to +5V output volt-
age, providing power supply to the positive analog supply
AVDD of the IC. Another MAX5084 (U1) provides a +12V
power supply to the positive analog supply of the mixed-
signal ports (AVDDIO) of the IC. For bipolar applications,
use an external power supply to provide negative voltage
for AVSSIO. See Figure 2.
Software Graphical User Interface (GUI)
The Munich software GUI is provided to facilitate evalua-
tion of the Pmod.

download the latest version of the Munich GUI software.
Refer to the MAX11300PMB1 peripheral module and
Munich (USB2PMB1) adapter board Quick Start Guide for
step-by-step evaluation using the Munich GUI.
External Power Supply
The on-board power supply provides 70mA max current
at VDDIO = +12V. If additional current is needed, use an
external power supply by removing the jumper connecting
VDDIO to +12V and connecting a +12V external power
supply to the VDDIO pin.
For bipolar applications, remove the jumper from VSSIO
pin to GND and connect a negative power supply to the
VSSIO pin. See Figure 2 and refer to the MAX11300 IC
data sheet for details.
External Temperature Sensors
Two-pin connector vertical headers, EXT_TEMP1 and
EXT_TEMP2, are provided to measure the environment
temperature. Connect the base and collector of diode-
connected transistors, such as the 2N3906 to the TEMP1
or TEMP2 pin and the emitter to the EXT pin to measure
the external temperature. See Figures 3 and 4.
