Part Details:

Dual LM1876 July 2003 20W Overture LM1876 OvertureTM Audio Power Amplifier Series Audio Dual 20W Audio Power Amplifier with Mute and StandbyModes Power TM General Description Key Specifications Audio The LM1876 is a stereo audio amplifier capable of delivering jTHD+N at 1kHz at 2 x 15W continuous average typically 20W per channel of continuous average outputpower into a 4 or 8 load with less than 0.1% THD+N. output power into 4 or 8: 0.1% (max) Amplifier Each amplifier has an independent smooth transition fade- jTHD+N at 1kHz at continuous average Power in/out mute and a power conserving standby mode which output power of 2 x 20W into 8: 0.009% (typ) can be controlled by external logic. jStandby current: 4.2mA (typ) The performance of the LM1876, utilizing its Self Peak In-stantaneous Temperature (°Ke) (SPiKeTM) protection cir-cuitry, places it in a class above discrete and hybrid amplifi- Features with Amplifier ers by providing an inherently, dynamically protected Safe n SPiKe protection Operating Area (SOA). SPiKe protection means that these n Minimal amount of external components necessary parts are safeguarded at the output against overvoltage, n Quiet fade-in/out mute mode undervoltage, overloads, including thermal runaway and in- Mute n Standby-mode stantaneous temperature peaks. n Isolated 15-lead TO-220 package n Non-Isolated 15-lead TO-220 package Series and n Wide supply range 20V - 64V Applications Standby n High-end stereo TVs n Component stereo n Compact stereo Connection Diagram Modes Plastic Package
