The MAX98091ETM+T is a fully integrated stereo audio codec designed for portable applications, offering a balance of high performance and ultra-low power consumption. Its flexible input scheme supports multiple analog or digital microphone and line inputs. The device features a digital audio interface supporting master or slave mode, with sample rates from 8kHz to 96kHz and standard PCM formats like I2S, left/right-justified, and TDM.
This audio codec incorporates FlexSound® technology DSP for advanced signal processing, including a biquad filter for recording and a seven-band parametric equalizer for playback to optimize loudspeaker performance. It includes stereo Class D speaker amplifiers capable of driving 4Ω and 8Ω loads efficiently, and a DirectDrive® stereo Class H headphone amplifier that eliminates the need for large DC-blocking capacitors. The device also features a differential receiver amplifier that can be reconfigured as a stereo single-ended line output.
Key electrical specifications include a 102dB dynamic range for the stereo DAC to headphone output and 99dB for the stereo ADC. Power consumption is remarkably low, with 4.1mW for stereo playback and 4.5mW for stereo recording. The device operates within a supply voltage range of 1.65V to 2V and has an operating temperature range of -40°C to 85°C.
The MAX98091ETM+T is available in a 48-TQFN (6x6) package, suitable for surface mounting. Its compact footprint and integrated features make it an excellent choice for space-constrained portable devices requiring high-quality audio.
