.ti. 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 Features - 23 SPi Ke Protection - Minimal Amount of External ponents Necessary - Quiet Fade-In/Out Mute Mode - Standby-Mode - Isolated 15-Lead TO-220 Package (PFM) - Non-Isolated 15-lead TO-220 Package - Wide Supply Range 20V - 64V APPLICATIONS - High-End Stereo TVs - ponent Stereo - pact Stereo KEY SPECIFICATIONS - THD+N at 1k Hz at 2 x 15W continuous averageoutput power into 4Ω or 8Ω: 0.1% (max) - THD+N at 1k Hz at continuous average output power of 2 x 20W into 8Ω: 0.009% (typ) - Standby current: 4.2m A (typ) 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) ( SPi Ke™) protection circuitry, places it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Operating Area (SOA). SPi Ke protection means that these parts are safeguarded at the output against overvoltage, undervoltage, overloads, including thermal runaway and instantaneous temperature peaks.
