General Description ?Key Specifications ?
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. ?jTHD+N at 1kHz at 2 x 15W continuous average output power into 4? or 8Ω: 0.1% ?
Each amplifier has an independent smooth transition fade-?jTHD+N at 1kHz at continuous average ?
