Analog Devices Inc./Maxim Integrated MAX98372TEVSYS#

Overview

MAX98372TEVSYS# from Maxim Integrated is an evaluation system for the MAX98372 digital input Class D speaker amplifier, supporting I²S/TDM/left-justified audio interfaces, dynamic headroom tracking, and automatic level control. It delivers up to 19W into 8Ω with dual supply rails (1.14–1.98V DVDD and 5.5–18V PVDD), enabling rapid validation of audio subsystems in portable and embedded speakers.

For engineers reviewing the MAX98372TEVSYS# datasheet, MAX98372TEVSYS# pinout, MAX98372TEVSYS# application, or MAX98372TEVSYS# equivalent, this kit provides USB-audio streaming, Windows 7+ GUI software, proven PCB layout, and full register-level control over the MAX98372 IC - all with single-supply operation and no external audio test equipment required.

Technical Context

The MAX98372TEVSYS# integrates two hardware boards: the MAX98372DEV# development board (featuring the TQFN-packaged MAX98372 IC) and the MAXAUDINT001# (AUDINT1) audio interface board. The AUDINT1 board supplies regulated DVDD (1.2/1.8/3.3V), generates MCLK, and bridges USB to both I²S (for audio playback) and I²C (for device configuration).

Communication is handled via a Windows-based GUI that reads/writes MAX98372 registers (0x01–0x51, 0xFF), monitors STATUS/STATE/FLAG interrupts, and supports configuration file (.98372) load/save. The system uses fixed I²C address 0x62 by default, configurable via on-board jumpers R7–R14.

FAQ

What does MAX98372TEVSYS# evaluate and how is it structured?

MAX98372TEVSYS# evaluates the MAX98372 digital input Class D speaker amplifier IC. It consists of two fully assembled PCBs: the MAX98372DEV# board hosting the TQFN-packaged IC, and the MAXAUDINT001# (AUDINT1) board providing USB-to-I²S/I²C conversion, DVDD regulation, and MCLK generation. Together they form a self-contained evaluation platform requiring only one external DC supply and a Windows PC.

Does MAX98372TEVSYS# require external audio test equipment?

No - MAX98372TEVSYS# eliminates the need for external audio generators or analyzers. Its AUDINT1 board converts USB audio streams (from Windows Media Player, iTunes, or other host applications) directly into I²S format for playback through the MAX98372 amplifier. Audio output is delivered to speaker terminals (OUTP/OUTN), and real-time device control is enabled via the included Windows GUI software.

What power supplies are needed to operate MAX98372TEVSYS#?

Only one external DC supply is required: 5.5V–18V at ≥2A connected to the PVDD binding posts on the MAX98372DEV# board. The AUDINT1 board internally generates all logic supplies - DVDD (1.2/1.8/3.3V) and VIO (1.8/3.3V) - via onboard LDOs. No additional voltage sources are needed for digital interface or control functionality.

How is the MAX98372 IC configured and monitored using MAX98372TEVSYS#?

Configuration and monitoring of the MAX98372 IC within MAX98372TEVSYS# is performed via Windows 7+ evaluation software that communicates over USB-to-I²C (via AUDINT1). The GUI provides tabbed access to all writable registers (0x01–0x51), live STATUS/STATE/FLAG interrupt monitoring, block-diagram-driven register editing, and .98372 configuration file import/export - all without requiring external debug probes or command-line tools.

Can the I²C address of the MAX98372 device in MAX98372TEVSYS# be changed?

Yes - the MAX98372 IC in MAX98372TEVSYS# defaults to I²C address 0x62, but supports 16 possible addresses (0x62–0x80) via ADDR0/ADDR1 pin strapping. On the MAX98372DEV# board, resistors R7–R14 allow selection of alternate addresses per Table 8 in the EV system documentation. Only one resistor pair should be installed at a time to ensure correct addressing and avoid bus conflicts.
