MAX9851 - Stereo Audio CODECs

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.

Key Features

  • voiceband digital filtering. 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, signal mixing, and operating modes is done through the I2C 2-wire interface. 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. Feat.
