MAX98091
General Description
The MAX98091 is a fully integrated audio codec whose
high-performance, ultra-low power consumption and
small footprint make it ideal for portable applications.
The device features a highly flexible input scheme with
six input pins that can be configured as analog or digital
microphone inputs, differential or single-ended line inputs,
or as full-scale direct differential inputs. Analog inputs can
be routed to the record path ADC or directly to any analog
output mixer.
The device accepts master clock frequencies of either
256 x f
S
or from 10MHz to 60MHz. The digital audio inter-
face supports master or slave mode operation, sample
rates from 8kHz to 96kHz, and standard PCM formats
such as I
2
S, left/right-justified, and TDM.
The record/playback paths feature FlexSound® technology
DSP. This includes digital gain and filtering, a biquad filter
(record), dynamic range control (playback), and a seven
band parametric equalizer (playback) that can improve loud-
speaker performance by optimizing the frequency response.
The stereo Class D speaker amplifier provides efficient
amplification, features low radiated emissions, supports
filterless operation, and can drive both 4Ω and 8Ω loads.
The DirectDrive® stereo Class H headphone ampli-
fier provides a ground-referenced output eliminating the
need for large DC-blocking capacitors. The device also
includes a differential receiver (earpiece) amplifier that
can be reconfigured as a stereo single-ended line output.
