MAX9850 EVALUATION KIT AVAILABLE Stereo Audio DAC with DirectDrive Headphone Amplifier General Description The MAX9850 is a low-power, high-performance stereo audio DAC with an integrated DirectDrive headphone amplifier. The MAX9850 is designed to meet the board space and performance requirements of portable devices such as cell phones and MP3 and portable DVD players. The MAX9850 uses Maxim’s DirectDrive headphone technology that produces a ground-biased analog audio output from a single supply, which allows for driving the headphones directly from the amplifier outputs without large DC-blocking capacitors. This feature saves board space, provides higher click/pop suppression, and improves low-frequency (bass) response.
