1 / 15 page LM4701 Overture™ Audio Power Amplifier Series 30W Audio Power Amplifier with Mute and Standby Modes General Description The LM4701 is an audio power amplifier capable of deliver- ing typically 30W of continuous average output power into an 8 Ω load with less than 0.1% (THD + N). The LM4701 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 LM4701, utilizing its Self Peak In- stantaneous Temperature (˚Ke) (SPiKe™) Protection Cir- cuitry, places it in a class above discrete and hybrid amplifi- ers by providing an inherently, dynamically protected Safe Operating Area (SOA). SPiKe Protection means that these parts are completely safeguarded at the output against over- voltage, undervoltage, overloads, including thermal runaway and instantaneous temperature peaks. Key Specifications n THD+N at 1 kHz at continuous average output power of 25W into 8 Ω: 0.1% (max) n THD+N from 20 Hz to 20 kHz at 30W of continuous average output power into 8 Ω: 0.08% (typ) n Standby current: 2.1 mA (typ) Features n SPiKe Protection n Minimal amount of external components necessary n Quiet fade-in/out mute function n Power conserving standby-mode n Non-Isolated 9-lead TO-220 package Applications n TVs n Component stereo n Compact stereo Typical Application Connection Diagram SPiKe™ Protection and Overture™ are trademarks of National Semiconductor Corporation.
