General Description
The MAX98089 is a full-featured audio codec whose high
performance and low power consumption make it ideal
for portable applications.
Class D speaker amplifiers provide efficient amplification
for two speakers. Low radiated emissions enable com-
pletely filterless operation. Integrated bypass switches
optionally connect an external amplifier to the transducer
when the Class D amplifiers are disabled.
The IC features a stereo Class H headphone amplifier
that utilizes a dual-mode charge pump to maximize effi-
ciency while outputting a ground referenced signal that
does not require output coupling capacitors.
The IC also features a mono differential amplifier that can
also be configured as a stereo line output.
Two differential analog microphone inputs are available as
well as support for two PDM digital microphones. Integrated
switches allow for an additional microphone input as well
as microphone signals to be routed out to external devices.
Two flexible single-ended or differential line inputs may be
connected to an FM radio or other sources.
Integrated FlexSoundK technology improves loudspeak-
er performance by optimizing the signal level and fre-
quency response while limiting the maximum distortion
and power at the output to prevent speaker damage.
Automatic gain control (AGC) and a noise gate optimize
the signal level of microphone input signals to make best
use of the ADC dynamic range.
The device is fully specified over the -40NC to +85NC
extended temperature range.
