MAX9591 Evaluation Kit
header J1 or the labeled test points. Reference outputs
OUT_REFU_H, OUT_REFU_L, OUT_REFL_H, OUT_REFL_L,
and DAC outputs OUT1, OUT7, OUT8, and OUT14 pro-
vide 400mA of peak current. DAC outputs OUT2–OUT6
and OUT9–OUT13 provide 200mA of peak current. Stay
within the MAX9591 IC ’s power rating. Refer to the
MAX9591 IC data sheet for more information.
The on-board resistor-divider network (R37–R41) gener-
ates the reference inputs (REFU_H, REFU_L, REFL_H,
and REFL_L). The user can also apply external refer-
ence voltages to the REFU_H, REFU_L, REFL_H, and
REFL_L PCB pads after removing R37–R41.
The EV kit uses a 9V to 20V DC power supply, connected
across the AVDD and AGND PCB pads, for powering the
EV kit application circuit. The EV kit might require up to
500mA of supply current depending on output loading.
Digital Supply Configuration
The MAX9591 EV kit provides two options to power the
MAX9591 digital supply input (DVDD). DVDD can oper-
ate from the 3.3V supply generated by the USB-to-I 2 C
interface circuit or from a user-supplied 2.7V to 5.5V
DC power supply connected across the DVDD and
DGND PCB pads. See Table 1 to configure DVDD
using jumper JU5.
Caution: Always ensure that DVDD is powered before
AVDD.
MAX9591 Slave Address Description
The MAX9591 I 2 C slave address can be set by jumper
JU6. The slave address can be set to one of four dif-
ferent addresses. See Table 2 for slave address
configuration.
Stand-Alone User-Supplied
I 2 C Communication
The EV kit can be used in stand-alone operation to
interface with a user’s I 2 C system without using a PC.
To use the MAX9591 EV kit with a user-supplied I 2 C
interface, perform the following steps:
1) Viewing Figure 6, cut the SDA, SCL, STD_REG, and
BANK_SEL traces immediately to the left of the cor-
responding PCB pad.
2) Disconnect the USB cable from the EV kit.
3) Move jumper JU5 shunt to pins 2-3.
4) Connect the positive terminal of a user-supplied 2.7V
to 5.5V DC power supply to the DVDD PCB pad and
the negative terminal to the nearby DGND PCB pad.
5) Install 2.2k Ω 0603 surface-mount resistors at loca-
tions R35 and R36 to pull up user-supplied signals
SDA and SCL to DVDD if needed.
6) Connect the user-supplied I 2 C interface signals,
general-purpose output (GPO) control signals, and
signal ground return to the EV kit PCB pads, as
shown in Table 3.
