Stereo Audio CODEC
with FlexSound Technology MAX9888
19-5235; Rev 1; 2/11
Simplified Block Diagram
General Description
The MAX9888 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.
DirectDrive headphone amplifiers provide a true
ground-referenced output, eliminating the need for
large DC-blocking capacitors. 1.8V headphone opera-
tion ensures low power consumption. The device also
includes a differential receiver amplifier.
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.
