KA2206B is a 2W stereo audio power amplifier integrated circuit which is produced by South Korea's Samsung, it is widely used in home audio, computer audio, car audio and some devices. 1, functions and features KA2206B integrated circuit contains two gain changeable preamplifiers and two power amplifiers. The input impedance is 25K, it can adjust the gain of amplifier by adjusting the capacity of ④, ⑨ foot external capacitance. The range of power voltage is 9-15V. When the power voltage are 12V, RL=4、THD=l0%, the output power of each audio channel is 2.3W. The typical application circuit of integrated block used in dual sound is shown in the figure 1-1. The typical application circuit of KA2206B integrated block used in BTL mode is shown in the figure 1-2. Then the output power is 4.7W. The figure 1-1 is the typical application circuit of KA2206B integrated block used in dual sound The figure 1-2 is the typical application circuit of KA2206B integrated block used in BTL mode
