TEXAS INSTRUMENTS TPA311 350-mW MONO AUDIO POWER AMPLIFIER handbook
The TPA311 is a bridge‑tied load (BTL) or single‑ended (SE) audio power amplifier designed for low‑voltage applications such as battery‑powered devices. It operates from a 2.5 V to 5.5 V supply and can deliver up to 350 mW into an 8 Ω load in BTL mode at 5 V, with THD+N of 0.5 %.
The device includes a shutdown mode (7 µA at 3.3 V, 60 µA at 5 V), integrated depop circuitry to eliminate speaker pop, and thermal/short‑circuit protection. It is offered in 8‑pin SOIC and PowerPAD MSOP packages, and the datasheet provides detailed electrical characteristics, typical performance graphs, and application notes.
