General Description
The MAX9851/MAX9853 are single-chip, stereo audio CODECs designed to provide a complete audio solution for a GSM/GPRS/EDGE cell phone. The MAX9851/MAX9853 provide stereo DirectDriveTM headphone amplifiers, a mono receiver speaker amplifier, stereo Class D speaker amplifiers (MAX9851 only), stereo differential 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 transducer/vibrator signal can be derived from digital audio.

Features
♦ +1.7V to +3.3V (Digital) and +2.6V to +3.3V (Analog) Operation

♦ 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
♦ 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 (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
♦ Flexible Shutdown Modes for Power Saving
♦ Comprehensive Headset Detection
♦ Ultra-Low Power Wake-Up on Headset Detection

Applications
   GSM/GPRS/EDGE Cell Phones
