The LM1876 is a stereo audio amplifier capable of delivering typically 20W per channel of continuous average output power. It features independent smooth transition fade-in/out mute and power conserving standby modes. The SPiKe Protection Circuitry provides dynamic protection. Key features include SPiKe Protection, minimal external components, quiet fade-in/out mute mode, standby mode, and a 15-lead TO-220 package.
The LM1876 Overture™ Audio Power Amplifier Series provides a stereo 20 W per channel solution with integrated mute and standby functions. It features National Semiconductor’s SPiKe™ protection circuitry, which safeguards the device against over‑voltage, under‑voltage, overloads and thermal spikes.
The datasheet includes electrical characteristics, typical application circuits, external component descriptions, performance graphs, and mechanical dimensions for both isolated (TF) and non‑isolated (T) TO‑220 packages.
