It integrates differential inputs, PWM modulation, short-circuit protection, and a depop feature that suppresses turn-on clicks. ## Supply range and output power — sizing the audio rail Rated for 2.4V to 5.5V, this part runs directly from a single Li-ion cell or a 3.3V/5V regulated rail. The 2.5W per channel into 4Ω is the headline number at the upper end of the supply range; at lower voltages the available power scales down proportionally. For a 3.7V Li-ion pack, expect roughly 1.5W to 2W per channel into 4Ω before clipping — enough for a loudspeaker in a portable Bluetooth speaker or a soundbar. The 16-DSBGA package is a fine-pitch wafer-level ball grid array — no leads, no exposed pads. It requires a solder-paste stencil matched to the 2.5x2.12 mm footprint and a reflow profile compatible with lead-free assembly.","metaTitle":"LM4674ATLX Class D Audio Amp, 2.5W x 2 @ 4Ω, DSBGA-16","metaDescription":"LM4674ATLX Boomer® Class D stereo amplifier, 2.5W per channel into 4Ω, 2.4V–5.5V supply, industrial temp, active production.","metaKeywords":null},"attributes":{"series":"Boomer®, PowerWise®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Class D","Series":"Boomer®, PowerWise®","Package":"Bulk","Features":"Depop, Differential Inputs, PWM, Short-Circuit Protection, Shutdown","Output Type":"2-Channel (Stereo)","Mounting Type":"Surface Mount","Package / Case":"16-WFBGA, DSBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"2.4V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"16-DSBGA (2.5x2.12)","Max Output Power x Channels @ Load":"2.5W x 2 @ 4Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.47","stockQuantity":0,"priceTiers":[{"qty":642,"price":"$0.47000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f895f9a54f5282c8ab330981ac353245.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output power per channel of LM4674ATLX?","answer":"The LM4674ATLX delivers 2.5W per channel into a 4Ω load, stereo output, at the rated supply voltage."},{"question":"What is the difference between LM4674ATLX and LM4674ATL?","answer":"The LM4674ATLX and LM4674ATL share the same Boomer® Class D amplifier core and 2.5W x 2 @ 4Ω output.
