It delivers 1.37 W per channel into 8 Ω speakers and 20 mW per channel into 32 Ω headphones, covering both loudspeaker and headphone drive from one IC. The I²C interface handles volume control, shutdown, and depop sequencing — no separate codec or analog pot needed for gain staging. ## Supply and temperature range Supply voltage spans 2.7 V to 5.5 V. Operating temperature range is -40°C to 85°C. ## Class D for speakers, Class G for headphones The Class D speaker path delivers 1.37 W per channel into 8 Ω. The Class G headphone amplifier delivers 20 mW per channel into 32 Ω.","metaTitle":"LM49251TLX/NOPB Boomer Class D/G Audio Subsystem, 30-DSBGA","metaDescription":"Texas Instruments LM49251TLX/NOPB stereo audio subsystem with Class D/G output, I²C volume control, 1.37W x 2 @ 8Ω.
