TPA302 Datasheet (Texas Instruments) - 300-mW STEREO AUDIO POWER AMPLIFIER

TPA302, 300-mW STEREO AUDIO POWER AMPLIFIER

The TPA302 is a stereo audio power amplifier capable of delivering 250 mW of continuous average power into an 8-Ω 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 Ω or headphones at 32 Ω.
