It integrates a mono speaker amplifier rated for 1.3W into 8Ω and a stereo headphone amplifier delivering 45mW per channel into 32Ω. ## Output power split — what it means for the BOM The 1.3W mono channel into 8Ω covers a small speaker driver for voice prompts or alert tones, while the 45mW stereo headphone output into 32Ω handles line-level or headphone listening. That split means a single IC replaces two separate amplifier stages, saving board area and reducing the passive count around the audio path. The I²C bus lets a host MCU adjust volume independently for speaker and headphones, which simplifies the control interface compared to analog-potentiometer designs. ## Lifecycle and sourcing The LM49101TMX/NOPB is listed as Active in production status.
