Stereo Audio CODEC

with FLEXSOUND Technology

General Description

The MAX9888 is a full-featured audio CODEC whose

high performance and low power consumption make it

ideal for portable applications.

Features

S 100dB DR Stereo DAC (8kHz < f < 96kHz)

S 91dB DR Stereo ADC (8kHz < f < 96kHz)

S Stereo Low EMI Class D Amplifiers

950mW/Channel (8I, V

= 4.2V)

SPKVDD_

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 DirectDrive Headphone Amplifiers

S Differential Receiver Amplifier

S 2 Stereo Single-Ended/Mono Differential Line

Inputs

S 3 Differential Microphone Inputs

DirectDrive headphone amplifiers provide a true

S FLEXSOUND Technology

5-Band Parametric EQ

ground-referenced output, eliminating the need for

large DC-blocking capacitors. 1.8V headphone opera-

tion ensures low power consumption. The device also

includes a differential receiver amplifier.

Automatic Level Control (ALC)

Excursion Limiter

Speaker Power Limiter

Speaker Distortion Limiter

Microphone Automatic Gain Control

and Noise Gate

Three differential analog microphone inputs are available

as well as support for two PDM digital microphones.

Integrated switches allow 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.

S Dual I²S/PCM/TDM Digital Audio Interfaces

S Asynchronous Digital Mixing

S Supports Master Clock Frequencies from 10MHz

to 60MHz

Integrated FLEXSOUNDK technology improves loud-

speaker performance by optimizing the signal level and

frequency response while limiting the maximum distor-

tion 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.

S RF Immune Analog Inputs and Outputs

S Extensive Click-and-Pop Reduction Circuitry

S I²C Control Interface

S 63 WLP Package (3.80mm x 3.30mm, 0.4mm Pitch)

Ordering Information

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

extended temperature range.
