MAX98095

Audio Hub with FlexSoundProcessor

General Description

Benefits and Features

S 102dB DR Stereo DAC (8kHz < f < 96kHz)

The MAX98095 is a full-featured high performance audio

hub with low power consumption and advanced signal

processing, making it ideal for a wide range of portable

applications.

S 90dB DR Stereo ADC (8kHz < f < 96kHz)

S 4.2mW Headphone Playback Power Consumption

S Stereo Low EMI Class D Amplifiers

3.2W per Channel (4I , PVDD� = 5.0V)

1.2W per Channel (8I , PVDD� = 4.2V)

S Stereo DirectDriveM Headphone Amplifiers

33mW per Channel (32I)

Three differential analog microphone inputs and four 1-bit

digital microphone inputs accept audio from main, acces-

sory, and background microphones. Analog line inputs

accept four single-ended or two differential audio signals.

S Differential Receiver Amplifier

Three digital audio interfaces support I²S/PCM/TDM

audio formats. Three integrated sample rate converters

and highly configurable signal routing enable a wide

range of use cases. The FlexSoundK audio processor

provides low-power advanced signal processing, includ-

ing equalization, dynamic range compression, speaker

protection, microphone noise suppression, acoustic

echo cancellation, and ambient aware outputs.

S 2 Stereo Single-Ended/Mono Differential Line

Inputs

S 3 Differential Microphone Inputs

S FlexSound Audio Processing

Enhanced Speakerphone

Single/Dual Microphone Noise Suppression

Ambient Aware Receiver Output

Acoustic Echo Cancellation

Integrated amplifiers can output signals from three DACs

or any of the analog inputs. Amplifiers include a differen-

tial receiver amplifier, a stereo Class D speaker amplifier,

a stereo Class H headphone amplifier and four single-

ended line outputs.

S Three I²S/PCM/TDM Digital Audio Interfaces

S Asynchronous Digital Mixing and Sample Rate

Conversion

S Extensive Click-and-Pop Reduction Circuitry

S I²C/SPI Control Interface

S 108 WLP Package (6.4mm x 4.7mm, 0.5mm pitch)

The IC is fully specified over the -40NC to +85NC extended

temperature.
