Analog Devices Inc./Maxim Integrated MAX98363BDEV#

Overview

MAX98363BDEV# from Analog Devices is a fully assembled and tested development board designed to evaluate the MAX98363B, a MIPI SoundWire v1.2–compliant Class-D mono audio amplifier in a 9-bump WLP (1.528mm × 1.528mm, 0.4mm pitch). It supports single-supply operation from 2.5V to 5.5V, delivers 3.2W into 4Ω at 5V, and features filterless output with 12.8μVRMS noise and 108.5dB dynamic range for compact portable audio systems.

For engineers reviewing the MAX98363BDEV# datasheet, MAX98363BDEV# pinout, MAX98363BDEV# application, or MAX98363BDEV# equivalent, this page provides verified hardware configuration details, jumper-based SoundWire Unique ID selection (0x5–0x9), external SoundWire manager interface requirements, and test-ready connections for OUTP/OUTN, SW_CLK/SW_DAT, and VDD power input.

Technical Context

The MAX98363BDEV# implements a dedicated evaluation platform for the MAX98363B IC, which uses MIPI SoundWire v1.2 for digital audio transport and register control. It requires an external SoundWire manager to drive SW_CLK and SW_DAT signals and does not include on-board audio generation or host interface logic.

Hardware configuration is managed via physical jumpers: J2 enables/disables the EN pin (VDD = active, GND = shutdown), and J9 sets the 4-bit SoundWire peripheral Unique ID (0x5–0x9) by connecting ADDR to GND, VDD, or through 100kΩ resistors. The board supplies DVDDIO internally via the MAX98363B's integrated LDO - no external DVDDIO source is needed.

FAQ

What is the primary function of the MAX98363BDEV#?

The MAX98363BDEV# is a development board used exclusively to evaluate the MAX98363B SoundWire v1.2–compliant Class-D mono amplifier IC. It provides all necessary circuitry, test points, and jumpers to configure, power, and interface the MAX98363B with an external SoundWire manager and audio measurement equipment - no onboard microcontroller or firmware is included.

Does the MAX98363BDEV# require an external DVDDIO supply?

No. The MAX98363BDEV# is configured for the MAX98363B variant, which integrates an internal LDO to generate DVDDIO from VDD. Unlike the MAX98363C/MAX98363D variants, no external 1.8V DVDDIO source or jumper J3 connection is needed - DVDDIO is automatically supplied and accessible at the test point.

How do I configure the SoundWire Unique ID on the MAX98363BDEV#?

Use jumper J9 to set the 4-bit SoundWire peripheral Unique ID for the MAX98363BDEV#. Per Table 2 in the reference documentation, shunt positions 5–3, open, 5–1, 5–4, or 5–2 select IDs 0x5, 0x6, 0x7, 0x8, or 0x9 respectively. This address must match the configuration expected by your external SoundWire manager during enumeration.

Can the MAX98363BDEV# be used without an external SoundWire manager?

No. The MAX98363BDEV# has no onboard SoundWire controller or host interface. It requires an external SoundWire manager (e.g., FPGA-based or SoC-hosted) to provide SW_CLK and SW_DAT signals, initialize registers, and stream digital audio. The included evaluation software operates only in non-interactive "Demo Mode" and cannot communicate with the board.

What speaker load and filtering are recommended for bench testing with the MAX98363BDEV#?

For bench testing, connect a 4Ω–8Ω speaker or resistive load directly to the OUTP/OUTN binding posts. When using speaker cables longer than ≈30 cm, add EMI filtering: Murata BLM18SG331TN1D ferrite beads (FB1/FB2) and 100pF capacitors (C9/C10) are validated for this board. Remove the factory-installed PCB traces shorting FB1/FB2 pads before installing filters.
