Part Details:

Dual LM4765 August 2000 30W Overture LM4765 OvertureTM Audio Audio Power Amplifier Series Dual 30W Audio PowerAmplifier with Mute and Standby Modes Power TM General Description Key Specifications Audio The LM4765 is a stereo audio amplifier capable of delivering jTHD+N at 1kHz at 2 x 25W continuous average typically 30W per channel of continuous average outputpower into an 8 load with less than 0.1% THD+N. output power into 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 30W into 8: 0.009% (typ) can be controlled by external logic. jStandby current: 6.5mA (typ) The performance of the LM4765, 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 Non-Isolated 15-lead TO-220 package n Wide supply range 20V - 66V Series and Applicationsn High-end stereo TVs Standby n Component stereo n Compact stereo Typical Application Connection Diagram Modes Plastic Package 10092702
