MAX98089

Low-Power, Stereo Audio Codec

with FlexSound Technology

General Description

Features

S 5.6mW Power Comsumption (DAC to HP at 97dB DR)

The MAX98089 is a full-featured audio codec whose high

performance and low power consumption make it ideal

for portable applications.

S 101dB DR Stereo DAC (8kHz < f < 96kHz)

S 93dB DR Stereo ADC (8kHz < f < 96kHz)

Class D speaker amplifiers provide efficient amplification

for two speakers. Low radiated emissions enable com-

pletely filterless operation. Integrated bypass switches

optionally connect an external amplifier to the transducer

when the Class D amplifiers are disabled.

S Stereo Low EMI Class D Amplifiers

1.7W/Channel (8I, V

2.9W/Channel (4I, V

= 5.0V)

SPK�VDD

S Efficient Class H Headphone Amplifier

S Differential Receiver Amplifier/Stereo Line Outputs

The IC features a stereo Class H headphone amplifier

that utilizes a dual-mode charge pump to maximize effi-

ciency while outputting a ground referenced signal that

does not require output coupling capacitors.

S 2 Stereo Single-Ended/Mono Differential Line

Inputs

S 3 Differential Microphone Inputs

S FlexSound Technology

5-Band Parametric EQ

The IC also features a mono differential amplifier that can

also be configured as a stereo line output.

Automatic Level Control (ALC)

Excursion Limiter

Two differential analog microphone inputs are available as

well as support for two PDM digital microphones. Integrated

switches allow for an additional microphone input as well

as microphone signals to be routed out to external devices.

Two flexible single-ended or differential line inputs may be

connected to an FM radio or other sources.

Speaker Power Limiter

Speaker Distortion Limiter

Microphone Automatic Gain Control

and Noise Gate

S Dual I²S/PCM/TDM Digital Audio Interfaces

S Asynchronous Digital Mixing

S Supports Master Clock Frequencies from 10MHz

Integrated FlexSoundKtechnology improves loudspeak-

er performance by optimizing the signal level and fre-

quency response while limiting the maximum distortion

and power at the output to prevent speaker damage.

Automatic gain control (AGC) and a noise gate optimize

the signal level of microphone input signals to make best

use of the ADC dynamic range.

to 60MHz

S RF Immune Analog Inputs and Outputs

S Extensive Click-and-Pop Reduction Circuitry

S Available in 63-Bump WLP Package (3.80mm x

3.30mm, 0.4mm Pitch) and 56-Pin TQFN Package

(7mm x 7mm x 0.75mm)

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