Overview
EVALUATION KIT AVAILABLE MAX98090 Ultra-Low Power Stereo Audio Codec General Description The MAX98090 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 (WLP) 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 fS or from 10MHz to 60MHz.
The digital audio interface supports master or slave mode operation, sample rates from 8kHz to 96kHz, and standard PCM formats such as I2S, 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 loudspeaker 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 amplifier 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.
