Analog Devices Inc./Maxim Integrated MAX98089EWY+

Overview

MAX98089EWY+ from Analog Devices is a low-power, stereo audio codec with integrated Class D speaker amplifiers (1.7W/channel into 8Ω), Class H headphone amplifier, dual I²S/PCM/TDM interfaces, and FlexSound™ technology for loudspeaker protection and enhancement. It supports 3 differential microphone inputs, 2 stereo line inputs, and operates across -40°C to +85°C for portable audio systems including smartphones and tablets.

For engineers reviewing the MAX98089EWY+ datasheet, MAX98089EWY+ pinout, MAX98089EWY+ application, or MAX98089EWY+ equivalent, key selection criteria include its 101dB DAC dynamic range, filterless Class D operation, 5-band parametric EQ, automatic gain control for microphones, and WLP-63 package compatibility with space-constrained PCB layouts.

Technical Context

The MAX98089EWY+ integrates asynchronous digital mixing between two independent audio data paths (DAI1/DAI2), enabling simultaneous playback and record with sample rate conversion. Its clock architecture supports master clock frequencies from 10MHz to 60MHz and tolerates jitter up to ±100ppm without audible artifacts.

FlexSound™ processing includes excursion limiting, speaker power limiting, and THD limiting - all implemented in hardware with configurable thresholds via I²C. The device uses dual-mode charge-pump-based Class H headphone drive to deliver ground-referenced outputs without coupling capacitors while maintaining >93dB ADC dynamic range at 48kHz sampling.

FAQ

What is the primary function of the MAX98089EWY+ in a portable audio system?

The MAX98089EWY+ serves as a full-featured stereo audio codec with integrated Class D speaker amplifiers, Class H headphone amplifier, dual I²S/PCM interfaces, and FlexSound™ speaker protection. In portable systems like smartphones and tablets, it handles analog-to-digital and digital-to-analog conversion, microphone preamplification, speaker/headphone drive, and real-time acoustic processing - consolidating multiple discrete functions into a single WLP-63 package.

Does the MAX98089EWY+ support filterless Class D operation?

Yes, the MAX98089EWY+ supports true filterless Class D operation for both left and right speaker outputs. Its low EMI design meets EN 55022 Class B emissions limits without external LC filters, reducing BOM cost and PCB area. This capability is verified across 4Ω and 8Ω loads at VSPKLVDD/VSPKRVDD = 3.7V and is enabled by proprietary modulation and layout techniques detailed in the "Filterless Class D Operation" section of the datasheet.

How many microphone inputs does the MAX98089EWY+ support, and what types are they?

The MAX98089EWY+ supports three differential analog microphone inputs (MIC1P/N, MIC2P/N, and INBDIFF) plus native interface for two PDM digital microphones. Each analog input includes programmable preamp gain (0–30dB), PGA (0–20dB), and dedicated MICBIAS (2.2V). The PDM interface operates independently on DAI1 or DAI2, allowing time-synchronized multi-mic acquisition for beamforming and noise suppression algorithms.

What package type is used for the MAX98089EWY+, and what are its key mechanical dimensions?

The MAX98089EWY+ uses a 63-bump Wafer-Level Package (WLP) with dimensions of 3.80mm × 3.30mm and 0.4mm bump pitch. This ultra-compact, face-down mounting package minimizes PCB footprint and height - critical for slim smartphones and wearables. The bump map and solder mask recommendations are specified in the "Package Information" section (p.129) of the official datasheet.

Can the MAX98089EWY+ be used with a 1.8V-only supply, or does it require multiple voltage rails?

The MAX98089EWY+ requires three distinct supply domains: 1.8V for DVDD/AVDD/PVDD digital/analog cores, 3.7V (2.8–5.5V range) for speaker amplifier supplies (VSPKLVDD/VSPKRVDD), and optional 3.3–5.5V for DVDDS1/DVDDS2 I/O buffers. While core logic runs at 1.8V, the speaker outputs demand higher voltage for adequate output power - so a dual-rail supply (1.8V + ≥3.7V) is mandatory for full functionality. The charge pump for headphone drive derives from HPVDD and HPVSS rails.
