Output power and supply — the decision drivers
At 325mW per channel into 8Ω, this amplifier is sized for headphone drivers, small alarm speakers, or auxiliary audio outputs — not for room-filling speakers. The 2.7V minimum supply means it runs directly from a single Li-ion cell without a boost converter, saving board space and BOM cost. The -40°C to 85°C temperature range covers industrial and outdoor portable equipment, not just indoor consumer gear.
Sourcing and lifecycle reality
The LM4880M carries an Active lifecycle status — no end-of-life notice, no last-time-buy window to watch. It remains a standard catalog item. For volume production or BOM freeze, we source against an RFQ through independent distribution; pricing and lead time are confirmed at quote time. No second-source alternate is listed on the official cross-reference, so plan for single-source procurement.
