The MAX98088 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.

Three differential analog microphone inputs are available

as well as support for two PDM digital microphones.

Integrated switches allow 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 loud-

speaker performance by optimizing the signal level and

frequency response while limiting the maximum distor-

tion 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.
