6) Enable all three power supplies.
Quick Start
Note: It is also possible to power the EV kits from a
single power supply to test electrical parameters, but
this invalidates the digital isolation between the A side
and the B side of the IC, and the isolation between U1
and U2.
Required Equipment
● MAX22701EVKIT# with MAX22701EASA+ as U1 and
U2, or MAX22702EVKIT# with MAX22702EASA+ as
U1 and U2
● One DC power supply with an output range up to 5.5V
● Two DC power supplies with an output range up to 36V
● Signal/function generator
7) Connect the signal/function generator output to
SMA connector INP_IN1. Set the function generator
output to be a square wave with the amplitude of
V

The MAX22701 and MAX22702 EV kits are fully assem-
bled and ready for evaluation. Follow the steps below to
verify board functionality:
10kHz frequency, and 50% duty cycle.
9) To measure the propagation delay matching between
U1 and U2, connect the function generator output to
both SMA connectors INP_IN1 and INP_IN2. Config-
ure the output to be a square wave with the amplitude

2) Connect the JA1 pin 3 (U1 EN) and pin 4 (GNDA1) to-
gether, and the JA2 pin 3 (U2 EN) and pin 4 (GNDA2)
together using shunts or jump wires to always enable
the U1 and U2 devices.
test point and OUT2 test point.
Note: When connecting one scope probe between
the OUT1 and VSSB1 test points and another scope
probe between the OUT2 and VSSB2 test points,
VSSB1 and VSSB2 are shorted together through the
oscilloscope, which invalidates the isolation between
U1 and U2. Make sure that VSSB1 and VSSB2 are
safe to be shorted together when probing OUT1 and
OUT2 using the same oscilloscope.
3) Connect a DC power supply between the EV kit
VDDA1 and GNDA1 test points. Set the output
between 3V and 5.5V.
4) Connect one DC power supply between the EV kit
VDDB1 and VSSB1 test points, and another DC pow-
er supply between VDDB2 and VSSB2 test points.
5) MAX22701 EV kit: set both DC power supply outputs
between 13V and 36V.
MAX22702 EV kit: set both DC power supply outputs
between 6V and 36V.
