Audio Hub with Wideband FlexSound Processor

The MAX98096 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.

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 supports standard PCM formats such as I²S, left justified, and TDM. Three integrated sample rate converters and highly configurable signal routing enable a wide range of use cases.The FlexSound® audio processor provides low-power advanced signal processing, including equalization, dynamic range compression, speaker protection, microphone noise suppression during wideband calls, acoustic echo cancellation, and ambient aware outputs.

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 117-bump WLP (6.9mm x 4.7mm x 0.5mm pitch) package is fully specified over the -40°C to +85°C extended temperature range.
