Maxim Integrated Digital Class-D Amplifier

Maxim Integrated’s MAX98360 are tiny and cost-effective amplifiers that combine Class D efficiency with industry-leading Class-AB audio performance. 

The amplifiers support I2S, left-justified, and TDM digital audio formats and automatically recognize the clocking scheme, eliminating the need for I2C programming and enabling a simple plug-and-play design. The interface accepts up to 32-bit data at sample rates up to 96kHz and is ideal for 1.2V and 1.8V logic while tolerating inputs up to 5.5V.  

The MAX98360 is available with or without turn-on and turn-off volume ramping. It also includes EMI-limiting features and a filterless spread-spectrum modulation scheme. The device is packaged in a 9-pin WLP with the pinout optimized for low-cost PCB fabrication.
