MAX44211 Evaluation Kit
Evaluates: MAX44211
General Description
The MAX44211 evaluation kit (EV kit) provides a proven
design to evaluate the MAX44211 high-current differential
line driver for powerline communications (PLC). The line
driver is an efficient low-distortion power amplifier that
provides high current to the low-impedance loads.
The MAX44211 EV kit printed circuit board (PCB) comes
with a MAX44211ETP+ in a 20-pin TQFN package.
Refer to the ZENOPLCEVK1# for a complete microcon-
troller and line driver evaluation platform.

Quick Start
Required Equipment
Before beginning, the following equipment is needed:
●● MAX44211 EV kit
●● +8V to +20V, 3A DC power supply
●● +2.7V to +5.5V, 100mA DC power supply
●● +3.3V, 100mA DC power supply
●● Function generator (Agilent 33220A)
●● Artificial mains network (line impedance stabilization
network) or a 50Ω load across OUT- and OUT-
Procedure
The MAX44211 EV kit is fully assembled and tested.
Follow the steps below to verify the board operation.
Caution: Do not turn on power supply until all con-
nections are made.
1) Connect the positive terminal of the +8V to +20V
supply to the AVDD test point and the negative termi-
nal of the supply to the nearest AGND test point.
2) Connect the positive terminal of the +2.7V to +5.5V
supply to the DVDD test point and the negative ter-
minal of the supply to the nearest DGND test point.
3) Connect the positive terminal of the +3.3V supply to
the VCC_U2 test point and the negative terminal of
the supply to the VEE_U2 test point.
4) Connect the artificial mains network to the OUT
connector.
5) Connect the signal from the function generator to the
SD_IN BNC.
6) Set the signal generator for 100mV_P-P, 0V offset,
and 100kHz sine wave.
7) Enable all supplies.
8) Enable function generator.
9) Observe the output signal from the artificial mains
network.
