19-6204; Rev 0; 4/12 EVALUATION KIT AVAILABLE MAX98095 Audio Hub with FlexSound Processor General Description Benefits and Features S 102dB DR Stereo DAC (8kHz < fS < 96kHz) The MAX98095 is a full-featured high performance audio hub with low power consumption and advanced signal processing, making it ideal for a wide range of portable applications. S 90dB DR Stereo ADC (8kHz < fS < 96kHz) S 4.2mW Headphone Playback Power Consumption S Stereo Low EMI Class D Amplifiers Three differential analog microphone inputs and four 1-bit digital microphone inputs accept audio from main, accessory, and background microphones. Analog line inputs accept four single-ended or two differential audio signals. S Three digital audio interfaces support I2S/PCM/TDM audio formats. Three integrated sample rate converters and highly configurable signal routing enable a wide range of use cases. The FlexSoundK audio processor provides low-power advanced signal processing, including equalization, dynamic range compression, speaker protection, microphone noise suppression, acoustic echo cancellation, and ambient aware outputs. S S S S Integrated amplifiers can output signals from three DACs or any of the analog inputs. Amplifiers include a differential receiver amplifier, a stereo Class D speaker amplifier, a stereo Class H headphone amplifier and four singleended line outputs.
