MAX98090 Stereo Codec

Maxim offers their MAX98090 small, ultra low-power, high-performance stereo audio codec

Image of Maxim Integrated's MAX98090 Stereo CodecMaxim’s MAX98090 is an integrated audio codec that has high-performance and ultra low-power consumption in a small footprint. These features make it ideal for portable applications. This codec has six input pins that can be configured as analog or digital microphone inputs, differential or single-ended line inputs, or as full-scale direct differential inputs.

The record and playback paths feature FlexSound® technology DSP. This DSP includes digital gain and filtering, a bi-quad filter (record), dynamic range control (playback), and a seven-band parametric equalizer (playback) that can improve loudspeaker performance by optimizing the frequency response. 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. The stereo Class D speaker amplifier provides efficient amplification, features low radiated emissions, supports filterless operation, and can drive both 4 Ω and 8 Ω loads.

Features
  • Three stereo single-ended/differential analog microphone/line inputs
