MAX98371 - Maxim Integrated

MAX98371 Digital Input Class D Speaker Amplifier

The MAX98371 is a high-efficiency, mono Class D audio amplifier featuring dynamic headroom tracking (DHT). DHT automatically optimizes the headroom available to the Class D amplifier as the power supply voltage varies, due to sudden transients and declining battery life to maintain a consistent listening experience. A wide 5.5V to 18V supply range allows the.
