19-3454; Rev 3; 4/06 EVALUATION KIT AVAILABLE Stereo Audio DAC with DirectDrive Headphone Amplifier MAX9850 General Description Features The MAX9850 is a low-power, high-performance stereo 1.8V to 3.6V Single-Supply Operation audio DAC with an integrated DirectDriveTM headphoneamplifier. The MAX9850 is designed to meet the board 30mW Stereo Headphone Output Power with space and performance requirements of portable devices 1.8V Supply such as cell phones and MP3 and portable DVD players. DirectDrive Outputs Eliminate DC-Blocking The MAX9850 uses Maxim s patented DirectDrive Capacitors headphone technology that produces a ground-biased 91dB PSRR at 1kHz analog audio output from a single supply, which allowsfor driving the headphones directly from the amplifier Any Master Clock Up to 40MHz outputs without large DC-blocking capacitors. This fea- ture saves board space, provides higher click/pop sup- Flexible I2S-Compatible Digital Audio Interface pression, and improves low-frequency (bass) response. I2C Headphone Volume and Mute Control The architecture does not require the headphone jackto be biased to a DC voltage and thus allows for a con- Stereo Line Inputs and Outputs ventional, grounded chassis design. Clickless/Popless Operation The MAX9850 s flexible clocking circuitry utilizes any 2-Wire (I2C)-Compatible Control Interface available system clock up to 40MHz, eliminating theneed for an external PLL and multiple crystal oscillators. Available in 28-Pin Thin QFN Package The DAC supports a wide range of sample rates from8kHz to 48kHz in both master and slave modes, making Ordering Information the MAX9850 the easiest to use and most versatile audioDAC available. It can also be operated like traditional PKG PART TEMP RANGE PIN-PACKAGE synchronous DACs, at any integer-oversampling ratio.
