LM3876 www.ti.com SNAS090D – APRIL 1995 – REVISED MARCH 2013 LM3876 Overture™ Audio Power Amplifier Series High-Performance 56W Audio Power Amplifier w/Mute Check for Samples: LM3876 FEATURES 1 23 56W Continuous Average Output Power into 8Ω 100W Instantaneous Peak Output Power Capability Signal-to-Noise Ratio ≥ 95 dB(Min) An Input Mute Function Output Protection from a Short to Ground or to the Supplies Via Internal Current Limiting Circuitry Output Over-Voltage Protection against Transients from Inductive Loads Supply Under-Voltage Protection, not Allowing Internal Biasing to Occur when |VEE| + |VCC| ≤ 12V, thus Eliminating Turn-On and Turn-Off Transients 11-Lead TO-220 Package Wide Supply Range 20V - 94V APPLICATIONS Component Stereo Compact Stereo Self-Powered Speakers Surround-Sound Amplifiers High-End Stereo TVs DESCRIPTION The LM3876 is a high-performance audio power amplifier capable of delivering 56W of continuous average power to an 8Ω load with 0.1% THD+N from 20Hz–20kHz. The performance of the LM3876, utilizing its Self Peak Instantaneous Temperature (°Ke) (SPiKe) protection circuitry, puts it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Operating Area (SOA). SPiKe protection means that these parts are completely safeguarded at the output against overvoltage, undervoltage, overloads, including shorts to the supplies, thermal runaway, and instantaneous temperature peaks.
