MAX15501 Evaluation Kit
The MAX15501 evaluation kit (EV kit) provides a proven
design to evaluate the MAX15501 analog output con-
ditioner that provides a programmable current up to
Q24mA, or a voltage up to Q12V proportional to a control
voltage signal. The EV kit also includes Windows 2000,
Windows XP-, and Windows Vista-compatible software
that provide a simple graphical user interface (GUI) for
exercising the features of the MAX15501.
The MAX15501 EV kit includes an on-board 16-bit DAC,
a +2.5V on-board reference, a +4.096V on-board ref-
erence, an on-board microcontroller, digital interface
headers, and an easy-to-use USB-PC connection.
The MAX15501 EV kit has two on-board voltage refer-
ences (+2.5V and +4.096V). Jumper JU18 allows the
user to select the reference voltage for both the on-
board DAC and the MAX15501. See Table 3 for jumper
descriptions.

By default, the analog signal input (AIN) of the MAX15501
connects to the output of an on-board 16-bit DAC
(MAX5138). The output of the DAC can be programmed
through the MAX15501 EV kit software. To apply an
external signal to the AIN input of the MAX15501, move
the shunt of JU13 to the 2-3 position and connect the
external signal to the AIN pad.
To use the MAX15501 EV kit with a user-supplied digital
interface, first move the shunts of jumpers JU1, JU2,
JU6–JU10, JU15, and JU16 to the 2-3 position. Then
connect the user-supplied digital signals to the J2 con-
nector. See Table 1 for the pin descriptions of the J2
connector.
Two power supplies are required to power up the
MAX15501 EV kit. Connect the positive power supply
(+15V to +32.5V) and the ground to the AVDD and the
AGND pads, respectively. Connect the negative power
supply (-15V to -32.5V) and the ground to the AVSS and
the AGND pads on the MAX15501 EV kit, respectively.
By default, the digital power-supply inputs of the
MAX15501 and the on-board DAC are powered from the
USB port. To apply a user-supplied digital power supply
to both of the MAX15501 and the on-board DAC, place
a shunt on jumper JU12 in the 2-3 position and connect
a +2.7V to +5.25V digital supply to the DVDD and the
DGND pads.
The MAX15501 EV kit includes four on-board sense
resistors RS1 (48.7I), RS2 (47.5I), RS3 (42.2I), and
RS4 (41.2I). See the jumper settings in Table 2 when
selecting the on-board sensing resistor.
