Analog Devices Inc./Maxim Integrated MAX98363DDEV#

Overview

MAX98363DDEV# from Analog Devices is a fully assembled and tested development board for evaluating the MAX98363D, a MIPI SoundWire v1.2–compliant Class-D mono audio amplifier in a 9-bump wafer-level package (1.528mm × 1.528mm, 0.4mm pitch). It supports single-supply operation from 2.5V to 5.5V (VDD), requires external DVDDIO at 1.7V–1.9V, and delivers 3.2W into 4Ω at 5V with 92% efficiency and 108.5dB dynamic range.

For engineers reviewing the MAX98363DDEV# datasheet, MAX98363DDEV# pinout, MAX98363DDEV# application, or MAX98363DDEV# equivalent, this board enables rapid validation of SoundWire audio streaming, click-and-pop suppression, filterless Class-D output performance, and configurable peripheral addressing via jumper J9 (Unique ID 0x5–0x9).

Technical Context

The MAX98363DDEV# interfaces directly with an external SoundWire manager via header J6 (SW_CLK, SW_DAT, GND) to configure registers and stream digital audio. It supports full SoundWire v1.2 protocol compliance, including 4-bit peripheral unique ID selection through ADDR pin strapping on jumper J9.

Hardware configuration includes jumper J2 for EN control (VDD = active, GND = shutdown), jumper J3 to enable the onboard 1.8V LDO (U2) for DVDDIO supply, and binding posts (OUTP/OUTN) for direct connection to 4Ω–8Ω loads - with optional EMI filtering using FB1/FB2 and C9/C10 for long cables.

FAQ

What is the primary function of the MAX98363DDEV#?

The MAX98363DDEV# is a dedicated development board for evaluating the MAX98363D SoundWire v1.2–compliant Class-D mono amplifier. It provides complete hardware infrastructure-including power conditioning, SoundWire interface headers (J6), configurable addressing (J9), and speaker output terminals-to validate digital audio streaming, power efficiency, THD+N, and dynamic range without custom PCB design. The MAX98363DDEV# does not operate standalone; it requires an external SoundWire manager for initialization and audio playback control.

How do I configure the MAX98363DDEV# for MAX98363D operation?

To configure the MAX98363DDEV# for MAX98363D, set jumper J2 to VDD (enable), install jumper J3 to connect the onboard MAX8887EZK18+ LDO to DVDDIO, and configure jumper J9 per Table 2 for Unique ID 0x5–0x9. Unlike MAX98363A/B variants, the MAX98363D requires external DVDDIO - either via the LDO (J3 closed) or bench supply (J3 open, voltage applied to DVDDIO test point). Confirm DVDDIO measures 1.7V–1.9V before powering VDD.

Does the MAX98363DDEV# include software that controls the hardware?

No. The MAX98363 evaluation software operates exclusively in "Demo Mode" and serves only as a visual reference for MAX98363D register maps and block diagrams. It does not communicate with, configure, or control the MAX98363DDEV# hardware in any way. Real-time register access and audio streaming require an external SoundWire manager connected to header J6 (SW_CLK, SW_DAT, GND), as specified in the MAX98363DDEV# user guide.

What load impedance is supported on the MAX98363DDEV# output?

The MAX98363DDEV# supports 4Ω to 8Ω loads via OUTP and OUTN binding posts. For Class-D output measurements, a switching amplifier measurement filter must be inserted between OUTP/OUTN/GND and the audio test equipment input. When connecting a speaker directly, a series inductor (33µH recommended) is required to suppress high-frequency content - especially critical when using cables longer than 30 cm to limit EMI radiation.

Can the MAX98363DDEV# be used to evaluate other MAX98363 variants?

The MAX98363DDEV# is specifically configured for the MAX98363D variant - distinguished by its requirement for external DVDDIO and Unique ID range 0x5–0x9. While physically similar to the MAX98363CDEV#, it is not interchangeable with MAX98363ADEV# or MAX98363BDEV# boards due to differences in DVDDIO architecture (internal LDO vs. external supply) and jumper-defined addressing. Each board variant maps precisely to its corresponding IC's electrical and configuration requirements.
