The TPA302 is a stereo audio power amplifier from TI that can deliver 300mW of continuous average power into an 8-ohm load at less than 0.06% THD+N from a 5-V power supply or up to 300mW at 1% THD+N.
The TPA302 is a 300‑mW stereo audio power amplifier from Texas Instruments, delivering up to 250 mW into 8 Ω loads at <0.06 % THD+N from a 5‑V supply, and 60 mW into 32 Ω loads for headphone applications. It includes shutdown control, internal mid‑rail generation, thermal and short‑circuit protection, and is offered in an 8‑pin SOIC package.
The datasheet provides absolute maximum ratings, recommended operating conditions (2.7‑5.5 V supply, 40‑85 °C ambient), electrical characteristics such as supply current, output power, THD, and typical application circuits with performance graphs.
