Low-Power, Stereo Audio Codec  
with FlexSound Technology  
MAX98089  
General Description  
The MAX98089 is a full-featured audio codec whose high  
performance and low power consumption make it ideal for  
portable applications.  
Features  
● 5.6mW Power Comsumption (DAC to HP at 97dB DR)  
● 101dB DR Stereo DAC (8kHz < f < 96kHz)  
S
● 93dB DR Stereo ADC (8kHz < f < 96kHz)

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.  
● Stereo Low EMI Class D Amplifiers  
1.7W/Channel (8Ω, V  
2.9W/Channel (4Ω, V  
= 5.0V)  
= 5.0V)

● Efficient Class H Headphone Amplifier  
● Differential Receiver Amplifier/Stereo Line Outputs  
● 2 Stereo Single-Ended/Mono Differential Line Inputs  
● 3 Differential Microphone Inputs  
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.  
● FlexSound Technology  
5-Band Parametric EQ  
Automatic Level Control (ALC)  
Excursion Limiter  
The IC also features a mono differential amplifier that can  
also be configured as a stereo line output.  
Speaker Power Limiter  
Speaker Distortion Limiter  
Microphone Automatic Gain Control  
and Noise Gate  
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.  
● Dual I2S/PCM/TDM Digital Audio Interfaces  
● Asynchronous Digital Mixing  
● Supports Master Clock Frequencies from 10MHz to  
60MHz  
Integrated FlexSound™ 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.  
● RF Immune Analog Inputs and Outputs  
● Extensive Click-and-Pop Reduction Circuitry  
● Available in 63-Bump WLP Package (3.80mm x  
3.30mm, 0.4mm Pitch) and 56-Pin TQFN Package  
(7mm x 7mm x 0.75mm)  
Ordering Information appears at end of data sheet.  
The device is fully specified over the -40°C to +85°C  
extended temperature range.
