LM1876 Datasheet Dual 20w Audio Power Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM1876 Overture™ Audio Power Amplifier Series Dual 20W Audio Power Amplifier with Mute and Standby Modes February 1998 LM1876 Overture™ Audio Power Amplifier Series Dual 20W Audio Power Amplifier with Mute and Standby.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LM1876 is a stereo audio amplifier capable of delivering typically 20W per channel of continuous average output power into a 4Ω or 8Ω load with less than 0.1% (THD + N).

Each amplifier has an independent smooth transition fade-in/ out mute and a power conserving standby mode which can be controlled by external logic.

The performance of the LM1876, utilizing its Self Peak Instantaneous Temperature (˚Ke) (SPiKe™) Protection Circuitry, places it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Operating Area (SOA).
