MAX20337 Evaluation Kit
General Description
Quick Start
The MAX20337 evaluation kit (EV kit) is a fully assembled
and tested circuit board that evaluates the MAX20337
beyond-the-rails SPDT analog switches. The EV kit
comes with the MAX20337ENT+ installed.
Required Equipment
● MAX20337 EV kit
● USB Cable or Power Supply
● Audio source (e.g., MP3 player, computer, etc.)
The EV kit features evaluation of the analog switches
through audio jack inputs and outputs, as well as SMA
connectors for AC characteristics. Input power to the EV
kit is provided by a Micro-USB, type-B connector, or an
external power supply.
● External speakers or headphones with 3.5mm audio
jack
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
Features
● USB Power Option
● SMA and 3.5mm Audio Jack Connectors
1) Connect a USB cable to J1 or power VB (TP1) with
5V power supply.
2) Verify that jumper JU4 has a shunt installed short-
ing pins 2–3. This shorts the control bit (CB) on the
devices to ground, electrically connecting NC1 to
COM1 and NC2 to COM2.
• Directly Evaluate AC Characteristics Through SMA
Connectors
• Quickly Evaluate Audio Performance with 3.5mm
Audio Jack Connectors
3) J2 is now connected to J3. Connect an audio source
to the normally closed audio jack J2, using a male-to-
male 3.5mm audio cable.
● Proven PCB Layout
● Fully Assembled and Tested
4) Connect external speakers or headphones to the
common audio jack J3.
EV Kit Contents
● EV Kit Board containing a MAX20337
5) When the audio source outputs the audio signal and
JU4 has a shunt shorting pins 2-3, the audio signal
should be heard on the speakers or headphones con-
nected at J3.
Ordering Information appears at end of data sheet.
6) Move the shunt on JU4 from pins 2–3 to pins 1–2.
Now CB is high, and J4 is connected to J3. The audio
signal should no longer be heard on the speakers or
headphones connected at J3.
7) If the audio source connection moves from the
normally closed audio jack (J2) to the normally open
audio jack (J4), the audio signal on the common audio
jack (J3) is heard on the speakers or headphones.

Power Supply
Detailed Description
The EV kit is powered by a user-supplied 1.6V to 5.5V
external DC power supply connected between VEXT
(TP3) and GND, the raw USB bus supplied at the micro-
USB connector (J1), or the regulated output of the LDO
(U3) that is powered by the USB bus.
The MAX20337 EV kit is a fully assembled and tested
circuit board evaluating the MAX20337 SPDT switches in
a 6-bump WLP package.
