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 patented 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 fea-
ture saves board space, provides higher click/pop sup-
pression, and improves low-frequency (bass) response.
The architecture does not require the headphone jack
to be biased to a DC voltage and thus allows for a con-
ventional, grounded chassis design.
The MAX9850’s flexible clocking circuitry utilizes any
available system clock up to 40MHz, eliminating the
need for an external PLL and multiple crystal oscillators.
The DAC supports a wide range of sample rates from
8kHz to 48kHz in both master and slave modes, making
the MAX9850 the easiest to use and most versatile audio
DAC available. It can also be operated like traditional
synchronous DACs, at any integer-oversampling ratio.
The audio DAC receives input data over a flexible
3-wire interface that supports up to 32 bits of left-justi-
fied, right-justified, or I
2
S-compatible audio data. Stereo
audio line inputs are provided to either mix analog
audio with the digital input stream, or to drive the head-
phone outputs directly. Mode settings, headphone
amplifier volume controls, and shutdown for both the
headphone and line outputs are programmed through a
2-wire, I
2
C-compatible interface.
The MAX9850 is fully specified over the -40°C to +85°C
extended temperature range and is available in a low-
profile, 28-pin thin QFN package (5mm x 5mm x 0.8mm).
