Part Details:

Stereo LM4780 July 2003 60W Overture LM4780 OvertureTM Audio Power Amplifier Series , Stereo 60W, Mono 120W Audio Power Amplifier with Mono Mute TM General Description Key Specifications 120W Audio The LM4780 is a stereo audio amplifier capable of typically n Output Power/Channel with 0.5% THD+N, 1kHz into delivering 60W per channel of continuous average output 8 60W (typ) power into an 8 load with less than 0.5% THD+N from n THD+N at 2 x 30W into 8 (20Hz - 20kHz) 0.03% (typ) 20Hz - 20kHz. Audio n THD+N at 2 x 30W into 6 (20Hz - 20kHz) 0.05% (typ) Power The LM4780 is fully protected utilizing National s Self Peak n THD+N at 2 x 30W into 4 (20Hz - 20kHz) 0.07% (typ) Instantaneous Temperature (°Ke) (SPiKeTM) protection cir- n Mute Attenuation 110dB (typ) cuitry. SPiKe provides a dynamically optimized Safe Operat- n PSRR 85dB (min) ing Area (SOA). SPiKe protection completely safeguards the n Slew Rate 19V/µs (typ) Power LM4780 s outputs against over-voltage, under-voltage, over- Amplifier loads, shorts to the supplies or GND, thermal runaway and Features instantaneous temperature peaks. The advanced protectionfeatures of the LM4780 places it in a class above discrete n SPiKe Protection and hybrid amplifiers. n Low external component count Amplifier Each amplifier of the LM4780 has an independent smooth n Quiet fade-in/out mute mode transition fade-in/out mute. n Wide supply range: 20V - 84V The LM4780 can easily be configured for bridge or parallel
