Texas Instruments TPA112 150‑mW Stereo Audio Power Amplifier Datasheet
The TPA112 is an 8‑pin PowerPAD™ MSOP stereo audio power amplifier capable of delivering 150 mW continuous RMS power per channel into 8‑Ω loads. It features a wide supply voltage range, external gain setting resistors, and integrated thermal and short‑circuit protection.
The device’s absolute maximum ratings include a supply voltage up to 5.5 V and an output current of +250 mA. Recommended operating conditions span 2.5‑5.5 V supply, –40 °C to 85 °C ambient, and typical THD+N below 0.1 % at 1 kHz into 8 Ω. Electrical characteristics such as input impedance (>1 MΩ) and supply current (1.5‑3 mA) are also specified.
