Product details

1.5W into 8Ω — what that means for the BOM

The 1.5W output into 8Ω is the guaranteed figure for BOM budgeting.

Active production — no LTB risk

The LM4861M/NOPB carries an Active lifecycle status and is ROHS3 compliant. No last-time-buy notice is in effect.

Thermal protection and shutdown

Built-in thermal protection shuts down the output stage if the die temperature exceeds the safe limit, protecting the amplifier and the speaker load during a fault. The shutdown pin (active-low) allows the system controller to force the amplifier into a low-power state. Mount the 8-SOIC with adequate copper pour on the PCB pads for heat spreading — the package relies on the board copper for thermal dissipation, not an external heatsink.

Frequently asked questions

Does LM4861M have thermal protection?

Yes, the LM4861M/NOPB includes thermal protection that shuts down the amplifier if the die temperature exceeds the safe limit.

What is the output power of LM4861M?

The LM4861M/NOPB delivers 1.5W into an 8Ω load from a single supply.
