The TPA6102A2 is a stereo audio power amplifier designed for battery applications. It features low supply current, shutdown current, and THD+N. The product can deliver 40mW of output power from a 3.3V supply into a 16-ohm load, with a THD+N of 0.08% at 1kHz and less than 0.2% across the audio band of 20Hz to 20kHz. For a 30mW output power into a 32-ohm load, the THD+N is less than 0.06% at 1kHz and less than 0.3% across the entire audio range.
The TPA6102A2 audio power amplifier is offered in 8‑pin SOIC and MSOP packages and delivers 50 mW continuous RMS power per channel into 16 Ω loads. It features an internally set 14 dB gain, low supply current (0.75 mA) and ultra‑low shutdown current (50 nA), making it suitable for battery‑powered applications.
The datasheet provides detailed electrical characteristics, recommended operating conditions, mechanical dimensions, and an important notice covering warranty, availability and safety‑critical usage restrictions.
