LM4937RL/NOPB from Texas Instruments is a 1.25-W, mono Class-D audio amp with 175-mW earpiece amp & 80-mW stereo headphone amp - General-purpose audio amplifiers. The LM4937 is an integrated audio sub-system designed for mono voice, stereo music cell phones connecting to base band processors with mono differential analog voice paths. Operating on a 3.3V supply, it combines a mono speaker amplifier delivering 520mW into an 8Ω load, a stereo headphone amplifier delivering 36mW per channel into a 32Ω load, and a mono earpiece amplifier delivering 55mW into a 32Ω load. It integrates the audio amplifiers, volume control, mixer, and power management control all into a single package. In addition, the LM4937 routes and mixes the single-ended stereo and differential mono inputs into multiple distinct output modes. The LM4937 features an I 2 S serial interface for full range audio and an I 2 C or SPI compatible interface for control. The full range music path features an SNR of 85dB with a 192kHz playback. Boomer audio power amplifiers are designed specifically to provide high quality output power with a minimal amount of external components.
