The mono channel delivers 2.1W into 4Ω; the headphone outputs each deliver 42mW into 32Ω. The headline output — 2.1W into 4Ω for the mono channel — is enough for a small speaker in a portable speaker dock, a handheld radio, or an industrial annunciator. The headphone output at 42mW per channel into 32Ω drives typical earbuds or headphones to a comfortable listening level. Because it is Class D, the efficiency is high (typically >85% at full power), which keeps the heat dissipation low in the 20-uSMD package — important when the board has no airflow. The I²C interface for volume and shutdown means you can route the control lines to a microcontroller without extra GPIO for analog volume pots.","metaTitle":"LM49150TL/NOPB Class D Audio Subsystem","metaDescription":"LM49150TL/NOPB Boomer® Class D audio subsystem: 2.1W mono speaker amp plus stereo headphone output, I²C volume control, -40°C to 85°C.
