Checking for live stock

The Texas Instruments LM4871M/NOPB is a robust mono Class-AB audio amplifier IC, designed to deliver high-quality 3 W of audio power into 3 Ω loads while operating from a low-voltage single supply of 2 V to 5.5 V. Encased in a compact SOIC‑8 SMD package, it’s optimised for space-conscious portable and embedded audio applications.

Crucial Features

Max Output Power: 3 W @ 3 Ω (10% THD).
Shutdown Current: ~0.6 µA, ideal for low-power standby.
Operating Temp Range: –40 °C to +85 °C.
Package: SOIC‑8 SMD (3.90 mm width).
Properties: Thermal shutdown protection, unity‑gain stable, no need for output coupling capacitors or snubber networks.

What Benefits Does It Offer to Users?

Minimal Bill of Materials: Requires few external components, eliminating coupling, bootstrap, and snubber capacitors, which simplifies design and reduces cost and board space.
Efficient Power Management: The low shutdown current makes it ideal for battery-operated or power-sensitive applications.
Reliable in Harsh Conditions: Wide operating temperature and robust thermal protection enhance reliability across industrial and portable audio designs.

Why Buy this Product?
