Maxim MAX98089 Stereo Audio Codec with FlexSound Technology

Maxim MAX98089 Stereo Audio Codec
with FlexSound Technology

Maxim MAX98089 TINI® Stereo Audio Codec with FlexSound™ technology is a full-featured device with high performance and low power consumption that make it ideal for portable applications. Maxim MAX98089 Stereo Audio Codec features a stereo Class D speaker amplifier for efficient amplification for two speakers. The Maxim MAX98089 also includes a stereo Class H headphone amplifier that utilizes a dual-mode charge pump to maximize efficiency while outputting a ground referenced signal that does not require output coupling capacitors. This Maxim audio IC provides a mono differential amplifier that can also be configured as a stereo line output. Integrated FlexSound technology improves loudspeaker performance by optimizing the signal level and frequency response while limiting the maximum distortion and power at the output to prevent speaker damage.
