Product details
Overview
MAX98088EWY+T from Maxim Integrated is a stereo audio codec with integrated Class D speaker amplifiers (950mW/channel), Class H headphone amplifier, dual I²S/PCM/TDM interfaces, FlexSound technology, and support for up to three differential microphone inputs. It delivers 101dB DAC dynamic range and 93dB ADC dynamic range at sample rates from 8kHz to 96kHz, targeting portable audio systems requiring low EMI, high fidelity, and speaker protection.
For engineers reviewing the MAX98088EWY+T datasheet, MAX98088EWY+T pinout, MAX98088EWY+T application, or MAX98088EWY+T equivalent, key selection considerations include its 63-bump WLP package (3.80mm × 3.30mm), asynchronous digital mixing capability, RF-immune analog I/O, click-and-pop suppression, and integrated speaker excursion/power/distortion limiting functions.
Technical Context
The MAX98088EWY+T implements a dual-path audio architecture with independent record and playback signal processing chains. Its FlexSound technology integrates five-band parametric EQ, automatic level control (ALC), excursion limiter, speaker power limiter, and distortion limiter - all configurable via I²C to protect loudspeakers while optimizing frequency response and loudness.
It supports two fully independent digital audio interfaces (DAI1/DAI2) with master/slave mode, asynchronous sample rate conversion, and flexible clocking (MCLK 10–60MHz). The analog front end includes programmable microphone preamps (0/20/30dB gain), noise gate, AGC, and RF-immune line inputs compatible with FM radio or auxiliary sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DAC Dynamic Range | 101dB at 8–96kHz sample rates - enables high-fidelity playback with minimal quantization noise in portable devices. |
| ADC Dynamic Range | 93dB at 8–96kHz - preserves voice and audio capture fidelity across wide input levels. |
| Class D Output Power | 950mW per channel into 8Ω at VSPKLVDD = 4.2V - drives small speakers without external amplification or output filters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar stereo audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AK4642EN | Lower DAC DR (98dB), no integrated Class D amps, requires external headphone driver, single I²S interface. | Suitable for cost-sensitive portable devices where speaker amplification is handled externally. | Select when system already includes discrete speaker drivers and lower power consumption is prioritized over integration. |
| TLV320AIC3106IRHBT | 94dB DAC DR, 1W Class AB headphone driver, no FlexSound, no speaker protection algorithms, 32-pin QFN package. | Better suited for industrial audio interfaces requiring robust analog I/O but no smart speaker processing. | Choose when design requires higher-voltage headphone drive (>2Vpp) and simpler register map without advanced loudspeaker management. |
Compared with AK4642EN and TLV320AIC3106IRHBT, the MAX98088EWY+T uniquely combines high-DR conversion, integrated Class D amplification, and hardware-accelerated speaker protection - reducing system-level complexity and enabling smaller form factors in consumer audio.

FAQ
What is the operating temperature range for the MAX98088EWY+T?
The MAX98088EWY+T is fully specified over the extended industrial temperature range of -40°C to +85°C. This ensures reliable operation in portable devices exposed to ambient thermal variations, including smartphones used outdoors or tablets deployed in uncontrolled environments. All electrical characteristics - including DAC/ADC dynamic range, THD+N, and speaker output power - are guaranteed across this full range.
Does the MAX98088EWY+T support PDM digital microphones?
Yes, the MAX98088EWY+T supports two PDM digital microphones via dedicated pins MIC1P/DIGMICDATA and MIC1N/DIGMICCLK. These pins operate in time-division multiplexed mode to accept PDM streams, eliminating the need for external decimation filters. The internal digital microphone interface includes clock generation, data alignment, and seamless integration into the ADC record path - confirmed in the Functional Diagram and Digital Microphone Timing Characteristics section of the datasheet.
How does FlexSound technology protect speakers in the MAX98088EWY+T?
FlexSound technology in the MAX98088EWY+T protects speakers using four coordinated hardware blocks: an excursion limiter that monitors cone displacement in real time, a power limiter that enforces thermal safe operating area, a distortion limiter that caps THD+N at user-defined thresholds, and a 5-band parametric EQ that reshapes frequency response to avoid resonant peaks. These functions operate autonomously without host CPU involvement and are configured via I²C registers.
What package type is used for the MAX98088EWY+T?
The MAX98088EWY+T uses a 63-bump Wafer-Level Package (WLP) with dimensions of 3.80mm × 3.30mm and 0.4mm ball pitch. This ultra-compact package is designed for high-density portable PCB layouts and supports standard reflow soldering processes. Pin configuration and solder mask recommendations are detailed in the "WLP Applications Information" section of the datasheet (page 121).
Can the MAX98088EWY+T drive both speakers and headphones simultaneously?
Yes, the MAX98088EWY+T can drive speakers and headphones simultaneously. Its independent playback path architecture allows concurrent operation of the Class D speaker amplifiers (SPKLP/SPKLN), Class H headphone amplifiers (HPL/HPR), and receiver/line outputs (RECP/RECN). Internal mixers and volume controls enable routing of different audio sources - such as media playback to speakers and voice call audio to headphones - without signal contention or crosstalk.
