MAX98390CEWX+T

Audio Amplifiers Overview

The MAX98390CEWX+T is a high-efficiency mono Class-D DSM smart amplifier featuring an integrated boost converter and Dynamic Speaker Management. It delivers up to 6.2W at 10% THD+N into a 4Ω load from a battery voltage as low as 2.65V. The maximum boost output is programmable from 6.5V to 10V in 0.125V increments. It supports I2S, left-justified, and 16-channel TDM formats with I2C control. The device operates over the extended -40°C to +85°C temperature range.

Audio Amplifiers Feature Summary

• Integrated Dynamic Speaker Management provides thermal protection, excursion protection, and an 8-band parametric equalizer.
• Patented active emissions limiting edge rate and overshoot control minimizes EMI and eliminates the need for output filtering.
• Flexible brownout-detection engine allows programmable current limiting, signal limiting, and clip functions to prevent battery voltage dips.
• Ultra-low noise floor of 10μV and dynamic range of 116dB ensure high-fidelity audio performance.
