With BTL(Bridge-Tied-Load) configuration, it delivers up to 2.7W/ch(5.4W in all) into a 3 ohm load or 2.3W/ch(4.6W in all) into a 4 ohm load or 1.5W/ch(3W in all) into an 8 ohm load. No external heat-sink is required. ♦ 2.2mA / Ch Quiescent Current at 5V For multiple-input applications, independent gain control and corner frequency can be implemented by summing the input sources through resistor ratio and input capacitor values. Automatic voltage gain control makes the best use of battery. ♦ Less Than 0.
