lm4780

The LM4780 is a stereo audio amplifier capable of delivering 60W per channel of continuous
average output power into an 8Ω load with less than 0.5% THD+N from 20Hz - 20kHz.

But in key specifications it is written:

*Output Power/Channel with 0.5% THD+N, 1kHz ; into 8Ω: 60 W (Typ)-----

*THD+N at 2 x 30W into 8Ω (20Hz - 20kHz):0.03% (Typ)
Do it deliver 60w at 20hz-20khz???
or 60w at 1khz????
And what does THD+N at 2 x 30W into 8Ω (20Hz - 20kHz):0.03% (Typ) means
  • Hi, Sheetal,

    Yes, it can deliver 60W from 20 Hz to 20 kHz. Kindly refer to Figure 12 of the data sheet.

    For your second question, kindly refer to Figure 9 of the data sheet. It basically means that the device can drive 30W per channel into an 8-ohm load with THD+N of "typically" 0.03%.
