The MAX98372 is a high-efficiency, mono Class D audioamplifier featuring dynamic headroom tracking (DHT)and brownout protection. DHT automatically optimizesthe headroom available to the Class D amplifier as thepower supply voltage varies, due to sudden transientsand declining battery life to maintain a consistent listeningexperience. A wide 5.5V to 18V supply range allows thedevice to reach 19W into an 8Ω load.The MAX98372’s flexible digital audio interface (DAI)supports I2S, left-justified, and TDM formats. The digitalaudio interface accepts 32kHz, 44.1kHz, 48kHz, 88.2kHz,and 96kHz sample rates with 16-/24-/32-bit data supportedfor all data formats. In TDM mode, the device cansupport up to 16 channels of audio data. A unique clockingstructure eliminates the need for an external MCLKsignal that is typically needed for PCM communication.This reduces pin count and simplifies board layout.Active emissions limiting with edge rate control minimizesEMI and eliminates the need for output filtering found intraditional Class D devices.An 8-bit PVDD supply voltage ADC enables the dynamicheadroom tracking circuit. DHT optimizes audio programpeak behavior as the supply voltage varies and providesflexible user-defined parameters.Thermal foldback protection ensures robust behaviorwhen the thermal limits of the device are exercised. Thecircuit can be enabled to automatically reduce the outputpower above a user specified temperature. This allows foruninterrupted music playback even at high ambient temperatures.Traditional thermal protection is also availablein addition to robust overcurrent protection.All MAX98372 control is performed using a standard2-wire, I2C interface. One of sixteen slave addresses canbe selected through two, four-level address pins. The IC isavailable in a 0.4mm pitch, 30-bump WLP and 32-pin TQFNpackages. It is specified over the extended, -40°C to +85°C temperaturerange.For similar function without brownout protection see MAX98371
