Analog Devices Inc./Maxim Integrated MAX98361CEVSYS#WLP

Overview

MAX98361CEVSYS#WLP from Analog Devices is a fully assembled evaluation system for the MAX98361C mono Class-D audio amplifier in WLP package, supporting I2S digital audio input, 5 selectable gains (–3dB to 12dB), and filterless 4Ω–8Ω speaker drive. It enables rapid USB-based audio playback testing with no external software or tools required.

For engineers reviewing the MAX98361CEVSYS#WLP datasheet, MAX98361CEVSYS#WLP pinout, MAX98361CEVSYS#WLP application, or MAX98361CEVSYS#WLP equivalent, this kit delivers out-of-box validation of PCM interface timing, gain configuration, TDM channel selection, and low-EMI Class-D output performance in portable audio designs.

Technical Context

The MAX98361CEVSYS#WLP integrates the MAX98361C DEV board and Audio Interface Board III (AUDINT3) to form a complete USB-to-PCM evaluation platform. The AUDINT3 provides 1.8V VDDIO via J1 and converts USB audio into I2S format compatible with the MAX98361C's native interface mode.

The DEV board supports standalone evaluation via DAI header J3 (BCLK, LRCLK, DIN), jumper-selectable gain (J4), and channel mapping (J6–J8), while enabling filterless operation with direct FOUTP/FOUTN speaker connections and configurable shutdown via SW1.

FAQ

What does MAX98361CEVSYS#WLP evaluate?

MAX98361CEVSYS#WLP evaluates the MAX98361C variant of the mono Class-D audio amplifier IC in WLP9 package. It validates I2S interface functionality, five-step hardware-selectable gain, left/right/mono channel routing, and filterless 4Ω–8Ω speaker drive - all using the included DEV board and AUDINT3 interface board.

Does MAX98361CEVSYS#WLP support TDM or left-justified audio modes?

No. MAX98361CEVSYS#WLP is configured specifically for the MAX98361C, which supports I2S mode only. TDM and left-justified modes are reserved for MAX98361D and MAX98361B variants respectively - neither is enabled or validated on this evaluation system.

How is power supplied to the MAX98361CEVSYS#WLP DEV board?

The MAX98361CEVSYS#WLP DEV board receives 1.8V VDDIO from the AUDINT3 board via J1 connector, and 2.5V–5.5V VDD via VIN binding post or optional 5V from AUDINT3 (for functional tests only). Jumper J5 selects between these VDD sources.

Can MAX98361CEVSYS#WLP be used without a PC or USB connection?

Yes. The MAX98361CEVSYS#WLP DEV board supports standalone evaluation: apply VDD and VDDIO externally, connect audio source to DAI header J3 (BCLK/LRCLK/DIN), configure gain and channel via jumpers J4/J6–J8, and drive speaker via FOUTP/FOUTN - no AUDINT3 or PC required.

What speaker load is supported by MAX98361CEVSYS#WLP?

MAX98361CEVSYS#WLP supports direct connection of 4Ω or 8Ω speakers to the FOUTP and FOUTN binding posts. Its filterless Class-D architecture eliminates need for external LC filters, enabling compact PCB layout - verified per MAX98361C datasheet specifications.
