Detailed Description
The MAX4298/MAX4299 are audio system ICs de-
signed for single +5V applications. The MAX4299 has a
stereo headphone driver, a microphone amplifier, and
a 100mA +3.3V linear regulator; the MAX4298 has the
stereo headphone driver only. The MAX4298/MAX4299
are designed specifically for harsh digital environments
where board space is at a premium 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. These devices are 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. They are
fully compliant to PC99 standards. Figure 1 is the

REG
Regulator Output. Bypass REG to GND with a 10
F
capacitor.

FB
Regulator Feedback. Internal resistors from this point
to REG and GND define the regulator output value.
Adjustments can be made to the output value by
adding resistors in the same place externally.

BIAS
Bias Point for Amplifiers. Bypass BIAS to GND with a
1
F capacitor.

SVCC
Standby Power Supply. Connect to a standby +5V
supply that is always on, or bypass with 220
F and
connect a Schottky diode from VCC to SVCC. Short to
VCC if clickless power-down is not essential.
