The TPA6111A2 is a stereo audio power amplifier packaged in either an 8-pin SOIC or an 8-pin PowerPAD™ MSOP package capable of delivering 150 mW of continuous RMS power per channel into 16-Ω loads.
The TPA6111A2 is a 150‑mW stereo audio power amplifier available in 8‑pin SOIC and MSOP packages. It is fully specified for 3.3 V operation and can deliver up to 150 mW continuous RMS power per channel into a 16 Ω load. The device includes pop‑reduction circuitry, internal mid‑rail generation, and thermal and short‑circuit protection.
The datasheet provides absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, typical application circuits, and performance graphs such as THD+N, supply‑ripple rejection, output noise and crosstalk. An important notice at the end outlines warranty, safety‑critical usage restrictions and legal considerations.
