Product details
Overview
MAX9880AETM+T from Maxim Integrated is a low-power, high-performance stereo audio codec IC designed for portable consumer applications including smartphones and tablets. It operates from a single 1.8V supply, supports dual I²S/TDM digital audio interfaces (one voiceband-optimized, one high-fidelity), delivers 96dB DAC dynamic range at 48kHz, and integrates stereo differential microphone inputs compatible with analog or digital microphones.
For engineers reviewing the MAX9880AETM+T datasheet, MAX9880AETM+T pinout, MAX9880AETM+T application, or MAX9880AETM+T equivalent, key selection considerations include its dual-interface clocking flexibility (10–60MHz master clock), capacitorless headphone amplifier option, voiceband-specific digital filtering with >70dB stopband attenuation, and I²C/SPI programmability with 3.6V-tolerant control inputs.
Technical Context
The MAX9880AETM+T implements two independent digital audio interfaces: Interface 1 optimized for low-latency voiceband operation (e.g., GSM packet-aware filtering), and Interface 2 supporting high-performance stereo playback up to 96kHz. Both support I²S and TDM formats with configurable sample rates (ADC: 8–48kHz; DAC: up to 96kHz) and synchronous/asynchronous master/slave clocking modes.
Its digital signal path includes user-configurable IIR highpass filters (5th-order, programmable cutoffs for 8/16kHz GSM + 217Hz notch) and lowpass voice filters (6× interpolation, 75dB stopband attenuation), alongside a battery-measurement auxiliary ADC and comprehensive headset detection circuitry with debounce and jack-sense weak pullup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DAC Dynamic Range | 96dB at 48kHz - enables high-fidelity music playback with minimal quantization noise in portable battery-constrained systems |
| ADC Dynamic Range | 82dB at 48kHz - supports clear voice capture with sufficient SNR for telephony and voice assistant use cases |
| Supply Voltage | 1.65V to 1.95V (AVDD/DVDD/PVDD) - ensures compatibility with modern 1.8V system rails and low-power operation |
| Digital Audio Interfaces | Two independent I²S/TDM interfaces - allows simultaneous voice call (Interface 1) and media playback (Interface 2) without multiplexing overhead |
| Microphone Input Support | Stereo differential analog or digital (PDM/SPDM) - eliminates need for external PDM-to-I²S bridge in designs using digital MEMS mics |
| Headphone Amplifier Modes | Differential (30mW), single-ended, or capacitorless (10mW) - reduces BOM cost and PCB area by removing DC-blocking capacitors |
| Voiceband Filtering | Programmable 5th-order IIR highpass + lowpass filters with >70dB stopband attenuation - suppresses GSM burst noise and improves voice clarity in cellular environments |

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 | Single I²S interface; no dual-TDM support; 94dB DAC DR; requires external 3.3V LDO for I/O | Limited to mono voice + stereo playback on shared interface; lacks GSM-specific filtering | Choose for cost-sensitive designs where dual-interface concurrency is unnecessary and external power management is acceptable |
| TLV320AIC3106IRHBT | Single I²S/TDM interface; 92dB DAC DR; 1.8V/3.3V dual-supply I/O; no capacitorless headphone mode | Requires four 220µF DC-blocking caps; no integrated headset debounce logic | Prefer when interfacing with legacy 3.3V processors and when board space permits traditional headphone amplifier implementation |
Compared with AK4642EN and TLV320AIC3106IRHBT, the MAX9880AETM+T uniquely delivers dual independent audio interfaces with GSM-optimized filtering, capacitorless headphone drive, and fully integrated headset detection - enabling smaller, lower-power, and more robust voice+media solutions in next-gen portable devices.

FAQ
What is the maximum DAC sample rate supported by the MAX9880AETM+T?
The MAX9880AETM+T supports DAC operation up to 96kHz, enabling high-resolution audio playback for premium portable media applications. This capability is confirmed in the Electrical Characteristics table under "DAC" parameters, where dynamic range and THD are specified at 48kHz and 96kHz sample rates. The device achieves 96dB dynamic range at 48kHz and maintains high fidelity at higher rates, making MAX9880AETM+T suitable for both standard-definition and high-definition audio use cases in smartphones and tablets.
Does the MAX9880AETM+T support digital microphones?
Yes, the MAX9880AETM+T supports stereo digital microphones via its MICLP/MICLN and MICRP/MICRN pins, which accept PDM (Pulse Density Modulation) or SPDM (Serial Pulse Density Modulation) data streams. The datasheet explicitly states "Stereo Microphone Inputs Support Digital Microphones" in the Features section and provides timing diagrams and register maps for SPDM configuration. This eliminates the need for external PDM-to-I²S bridges and simplifies integration with modern MEMS digital mics in MAX9880AETM+T-based designs.
What package type is used for the MAX9880AETM+T?
The MAX9880AETM+T uses a 48-pin, 6mm × 6mm, 0.4mm-pitch TQFN (Thin Quad Flat No-lead) package with exposed thermal pad. This is confirmed in the General Description ("available in … 48-pin, 6mm x 6mm TQFN packages") and Ordering Information section of the datasheet. The TQFN package provides superior thermal performance (θJA = 27°C/W) compared to the WLP variant, making it ideal for sustained audio playback in thermally constrained portable enclosures.
Can the MAX9880AETM+T operate with a 13MHz master clock?
Yes, the MAX9880AETM+T supports master clock frequencies from 10MHz to 60MHz, and 13MHz is explicitly used as the test condition in multiple Electrical Characteristics tables (e.g., DAC THD, PSRR). The flexible clocking architecture eliminates the need for external PLLs or crystal oscillators, allowing direct use of existing SoC system clocks. This capability is central to MAX9880AETM+T's low-power, space-saving design philosophy for portable applications.
Does the MAX9880AETM+T include headset detection functionality?
Yes, the MAX9880AETM+T integrates comprehensive headset detection with dedicated pins (JKSNS), registers (JDETEN, IJDET, JDWK, JDEB), and hardware logic. It supports mechanical switch detection, impedance measurement, and debounce timing (configurable via JDEB register). The datasheet includes a full "Headset Detection Overview" section and Figure 8 ("Typical Configuration for Headset Detection"), confirming that MAX9880AETM+T provides autonomous, low-latency plug/unplug recognition without host processor intervention.
