Applications/Uses

Description

The MAX98095 is a full-featured audio hub with Maxim's FlexSound® digital signal processor. This highly integrated device provides three I²S/PCM interfaces and powerful, high-performance amplifiers. The FlexSound DSP offers best-in-class noise suppression, echo cancellation, speaker protection, and ambient-aware algorithms to handle all the audio processing needs of portable devices. So you get the highest integration and audio quality possible.

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. 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.

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 single-ended line outputs.

The IC is fully specified over the -40°C to +85°C extended temperature.
