1 / 27 page LM1876 www.ti.com SNAS097C – MAY 1999 – REVISED APRIL 2013 LM1876 Overture™ Audio Power Amplifier Series Dual 20W Audio Power Amplifier with Mute and Standby Modes Check for Samples: LM1876 1 FEATURES DESCRIPTION The LM1876 is a stereo audio amplifier capable of 23 • SPiKe Protection delivering typically 20W per channel of continuous • Minimal Amount of External Components average output power into a 4 Ω or 8Ω load with less Necessary than 0.1% THD+N. • Quiet Fade-In/Out Mute Mode Each amplifier has an independent smooth transition • Standby-Mode fade-in/out mute and a power conserving standby mode which can be controlled by external logic. • Isolated 15-Lead TO-220 Package (PFM) • Non-Isolated 15-lead TO-220 Package The performance of the LM1876, utilizing its Self Peak Instantaneous Temperature (°Ke) ( SPiKe™) • Wide Supply Range 20V - 64V protection circuitry, places it in a class above discrete and hybrid amplifiers by providing an inherently, APPLICATIONS dynamically protected Safe Operating Area (SOA). • High-End Stereo TVs SPiKe protection means that these parts are safeguarded at the output against overvoltage, • Component Stereo undervoltage, overloads, including thermal runaway • Compact Stereo and instantaneous temperature peaks. KEY SPECIFICATIONS • THD+N at 1kHz at 2 x 15W continuous averageoutput power into 4 Ω or 8Ω: 0.1% (max) • THD+N at 1kHz at continuous average output power of 2 x 20W into 8 Ω: 0.009% (typ) • Standby current: 4.2mA (typ) Connection Diagram Figure 1.
