Due to its high power capability, the TDA2050 is capable of delivering up to 35W rms into 4 ohm loads at THD = 10%, VS = 18V, f = 1KHz, and up to 32W into 8 ohm loads at THD = 10%, VS = 22V, f = 1KHz. In addition, at VS=22.5V, f = 1KHz, the TDA 2050 can typically deliver 50W of music power into a 4 ohm load in 1 second.
