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

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 1.5V

with 0.0008% THD+N. They can also drive 32

phones to 1.2V

linear regulator can output 100mA of current. The

MAX4298 is available in a tiny 10-pin µMAX while the

MAX4299 is available in the space-saving 16-pin

TSSOP package.
