The LM4951SD/NOPB is a Texas Instruments Boomer® Class AB audio amplifier delivering 1.8W into an 8Ω load from a single mono channel.
The 10-WSON exposed-pad package (4x4 mm) requires a thermal land pattern on the PCB to draw heat from the die.

The LM4951SD/NOPB delivers 1.8W into an 8Ω load from a single mono channel. This is the maximum output power per channel at the specified load impedance.
Yes, the LM4951SD/NOPB integrates shutdown, thermal protection, and depop (pop-reduction) circuitry. Shutdown is controlled via a logic-level pin; thermal protection prevents die overheating under fault conditions.
Yes, the 2.7V to 9V supply range includes 5V. At 5V the amplifier delivers its rated 1.8W into 8Ω with sufficient headroom.
Yes, the NOPB suffix indicates RoHS3 compliance (lead-free and exempt under current EU RoHS directives).
