What are the key features of MAX98390EWX+T?
- Mono Class D amplifier with integrated Dynamic Speaker Management (DSM) protecting speakers from thermal damage and over-excursion without external DSP
- Digital I2S audio input eliminates DAC and analog routing, reducing system BOM and PCB area in mobile and smart speaker designs
- Ultra-compact 36-ball WLCSP measuring 2.42 x 2.61 mm enabling amplifier integration in thin smartphones and true wireless earbuds
- On-chip impedance and temperature sensing feeds DSM algorithms, maximizing loudness while keeping the speaker within safe operating limits at all volume levels
What is MAX98390EWX+T used for?
MAX98390EWX+T is designed for mobile handsets, smart speakers, and portable Bluetooth audio products where a high-efficiency Class D amplifier with speaker protection is required in a sub-7 mm² package. The built-in Dynamic Speaker Management replaces external DSP-based speaker protection, reducing system cost and latency in consumer audio systems. Its I2S interface connects directly to application processors and audio codecs common in Android and IoT voice assistant platforms.

Frequently Asked Questions
How does MAX98390EWX+T's Dynamic Speaker Management protect speakers in high-volume consumer audio designs?
Dynamic Speaker Management in MAX98390EWX+T continuously measures speaker impedance and voice-coil temperature using on-chip sense circuits, then applies real-time gain limiting to keep excursion below Xmax and coil temperature below rated limits. This allows the speaker to operate at maximum loudness with less than 1 dB margin to damage, extending speaker life in compact 1 W to 5 W portable speaker assemblies without an external DSP.
What digital audio interface does MAX98390EWX+T support and how does it simplify SoC integration?
MAX98390EWX+T accepts a standard I2S digital audio stream at sample rates from 8 kHz to 96 kHz, connecting directly to the I2S output of application processors and Bluetooth SoCs without an intermediate analog DAC. This eliminates analog routing susceptible to radiated noise, reduces PCB layers, and allows gain and DSM parameters to be configured over I2C at 400 kHz, simplifying integration in Android-based smartphones and smart speakers.
When is MAX98390EWX+T a better choice than a traditional analog Class AB amplifier for a portable speaker design?
MAX98390EWX+T's Class D topology achieves efficiency above 85% at typical output levels, compared to 40% to 60% for Class AB, extending battery life in a 2000 mAh portable speaker by several hours per charge cycle. Its 36-ball WLCSP package at 2.42 x 2.61 mm is 60% smaller than equivalent TQFN analog amplifiers, freeing board space for larger batteries or additional audio processing in constrained portable audio product enclosures.
