Stereo Audio CODECs with Microphone, DirectDrive

Headphones, Speaker Amplifiers, or Line Outputs

General Description

Features

♦ +1.7V to +3.3V (Digital) and +2.6V to +3.3V

The MAX9851/MAX9853 are single-chip, stereo audio

CODECs designed to provide a complete audio solu-

tion for a GSM/GPRS/EDGE cell phone. The MAX9851/

MAX9853 provide stereo DirectDrive^TMheadphone

amplifiers, a mono receiver speaker amplifier, stereo

Class D speaker amplifiers (MAX9851 only), stereo dif-

ferential line outputs (MAX9853 only), microphone input

amplifiers, plus flexible input selection and gain control.

Two serial digital audio interfaces are included, one

intended to accept voiceband data and the other

accepting I²S data. The voiceband interface can be

reconfigured as needed to act as a secondary I²S feed

input—allowing multiple audio source mixing of ringer

tones or other audio at different sample rates. A trans-

ducer/vibrator signal can be derived from digital audio.

(Analog) Operation

♦ +2.6V to +5.5V Class D Speaker Amplifier

Operation (Direct from Battery)

♦ Low 26mW Quiescent Power Consumption

(Playback)

♦ High 98dB Power-Supply Rejection Ratio

♦ 8kHz to 48kHz Sample Rate (Replay and Record)

♦ Stereo 18-Bit ADC and DAC

♦ Low-Noise Stereo Microphone Inputs and Stereo

Line Inputs

♦ Dual Source Digital Mixing (DAC)

♦ Selectable Voiceband Filter for

Recording/Playback Modes

The stereo digital-to-analog converter (DAC) path

includes filtering and mixing, programmable-gain ampli-

fiers (PGA), soft muting, and optional voiceband digital

filtering. The MAX9851/MAX9853 accept up to two digital

audio inputs at different sample rates. All analog inputs

have PGAs on the front end, allowing dynamic range

optimization with a wide range of input sources.

♦ Digital Filtering, Soft Mute, and Volume Control

♦ Low-Noise, High-PSRR Microphone Bias

Generator

♦ Stereo DirectDrive Headphone Amplifier

(2 x 50mW)

♦ Mono DirectDrive Handset Receiver Amplifier

The stereo analog-to-digital converter (ADC) converts

audio signals from either internal or external microphones

or stereo line inputs. The microphone amplifiers have a

programmable gain from 0 to 40dB to handle both ampli-

fied microphones and electret modules. In addition to a

digital highpass filter to remove DC offset voltages, the

ADC also features voiceband digital filtering.

(1 x 105mW)

♦ Stereo Class D, Ultra-Low-EMI, Filterless Speaker

Amplifier with Active Emissions Limiting

(2 x 1.25W, 8Ω) (MAX9851)

♦ Stereo Differential Line Output Amplifiers

(MAX9853)

♦ Clickless/Popless Operation

The digital audio interfaces support a variety of serial

audio formats. The secondary serial audio interface has

an independent supply voltage to allow integration into

multiple supply systems. Control for volume levels, sig-

nal mixing, and operating modes is done through the

I²C 2-wire interface.

♦ Flexible Shutdown Modes for Power Saving

♦ Comprehensive Headset Detection

♦ Ultra-Low Power Wake-Up on Headset Detection

All circuitry is optimized for high PSRR. The MAX9851/

MAX9853 use a thermally efficient, space-saving 48-pin

thin QFN package (7mm x 7mm x 0.8mm) with an

exposed pad.
