MAX20328A Evaluation Kit

MAX20328A/MAX20328B

General Description

Quick Start

The MAX20328A evaluation kit (EV kit) is a fully assem-

bled and tested circuit for evaluating the MAX20328/

MAX20328A/MAX20328B MUX switch for USB-C audio

adapter applications. The device features automatic MIC-

GND orientation and headphone impedance detection,

Beyond-the-Rails™ signal capability, and surge protec-

tion on pins attached to the USB-C connector. This EV

kit enables fast and easy evaluation of the MAX20328/

MAX20328A/MAX20328B switches in USB-C audio appli-

cations.

Required Equipment

The following equipment is required to verify the basic

functionality of this EV kit:

● 5V capable power supply

● Host device with I C communication support

● DMM or continuity tester

Optional Equipment

The following equipment can be used for more

complete testing of this EV kit:

The EV kit is populated with MAX20328A. The MAX20328,

MAX20328A, and MAX20328B are pin-to-pin and register

compatible. Users can install their own MAX20328 for

evaluation.

● USB Flash drive or other device with a USB-A male

connector

● USB A-to-B cable

● USB C cable

Features

● Automatic MIC/GND Orientation Detection

● TRRS 3.5mm audio cable

• MIC Line Bias Check Safeguards Against Shorting

MIC to GND

● TRRS 3.5mm audio device with 3.5mm to USB-C

passive adapter

● 3.5mm Audio Jack for Testing with Audio Signals

Procedure

● Onboard USB Receptacles for Passing and

The EV kit is fully assembled and tested. Follow the steps

below to verify board operation:

Measuring Data Signals

● Proven PCB Layout

1) Verify the positions of the conﬁguration resistor pairs

● Fully Assembled and Tested

R1 and R2, R4 and R5, and R6 and R8.

a) For evaluating MAX20328, R1, R4, and R6

should be installed.

b) For evaluating MAX20328A/MAX20328B, R2,

R5, and R8 should be installed.

Ordering Information appears at end of data sheet.

2) Verify shunts are installed on jumpers JU1 and on

JU3 in the 1-2 position. JU3 selects the source of the

supply.

3) Connect the positive lead of a 2.7 to 5V power supply

to TP12 and the negative lead to TP14, then safely

turn on the supply.

4) Connect SCL of the I C device to TP16 and SDA to

TP17; or use the 40-pin connector.

5) Read register 0x00 using the I C read address 0x2B.

If the data read matches the DEVICE_ID value of the

installed device (Table

of the MAX20328/

MAX20328A/MAX20328B data sheet), the EV kit is
