Features • SPiKe protection • Minimal amount of external components necessary • Quiet fade-in/out mute mode • Standby-mode • Isolated 15-lead TO-220 package • Non-Isolated 15-lead TO-220 package • Wide supply range 20V - 64V Description The LM1876 is a stereo audio amplifier capable of delivering typically 20W per channel of continuous average output power into a 4 or 8 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). SPiKe protection means that these parts are safeguarded at the output against overvoltage, undervoltage, overloads, including thermal runaway and instantaneous temperature peaks. Key Specification   THD+N at 1kHz at 2 x 15W continuous average   output power into 4 or 8: 0.1% (max)   THD+N at 1kHz at continuous average   output power of 2 x 20W into 8: 0.009% (typ)   Standby current: 4.2mA (typ) Applications • High-end stereo TVs • Component stereo • Compact stereo

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LM1876T	HV700	0	13850	0	0	1492500	3	423500950
LM1876TF	HV700	0	13850	0	0	1492500	3	423500950

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
