General Description
The MAX4298 and MAX4299 are audio system ICs
designed for single +5V applications. The MAX4299
features a stereo headphone driver, a microphone
amplifier, and a +3.3V linear regulator; the MAX4298
features the stereo headphone driver only. The
MAX4298/ MAX4299 are designed specifically for harsh
digital environments where board space is at a premi-
um and the digital power supply is noisy. The design
uses innovative design techniques to achieve ultra-high
power-supply rejection across the audio signal band
while, at the same time, delivering a high-current Rail-
to-Rail output drive capability. The chip is designed to
drive highly capacitive loads that may be encountered
when driving long cables to a remote load such as
desktop/notebook headphones or speakers. These
devices are fully compliant with PC99 standards.
The amplifiers exhibit 115dB of DC power-supply rejec-
tion and 80dB at 100kHz. The output amplifiers are
capable of driving a 1.5VRMS signal into a 10k load
with 0.0008% THD+N. They can also drive 32
head-
phones to 1.2VRMS with 0.02% distortion. At +3.3V, the
linear regulator can output 100mA of current. The
MAX4298 is available in a tiny 10-pin MAX while the
MAX4299 is available in the space-saving 16-pin
TSSOP package.
