The TPA302 is a stereo audio power amplifier capable of delivering 250 mW of continuous average power into an 8- load at less than 0.06% THD+N from a 5-V power supply or up to 300 mW at 1% THD+N. The TPA302 has high current outputs for driving small unpowered speakers at 8 W or headphones at 32 . For headphone applications driving 32- loads, the TPA302 delivers 60 mW of continuous average power at less than 0.06% THD+N. The amplifier features a shutdown function for power-sensitive applications as well as internal thermal and short-circuit protection. The amplifier TPA302 is available in an 8-pin SOIC (D) package that reduces board space and facilitates automated assembly.
