This is the datasheet of ti tpa301, which is a 350-mW mono audio power amplifier that supports 3.3v and 5v power supply. The output power is 350 mw at RL=8 ohm when the supply voltage is 5v, and 250 mw when the supply voltage is 3.3v. At the same time, the product has ultra-low quiescent current. In shutdown mode, it only has 0.15 microamps. In addition, it has thermal protection and short-circuit protection and supports soi and powerpad msol packaging.
The TPA301 is a bridge‑tied‑load (BTL) mono audio power amplifier designed for low‑voltage applications. It operates from 2.5 V to 5.5 V supplies and delivers up to 350 mW into an 8 Ω load, with ultra‑low quiescent current in shutdown mode (0.15 µA). The device includes thermal and short‑circuit protection and is available in SOIC and PowerPAD™ MSOP surface‑mount packages.
The datasheet details absolute maximum ratings, recommended operating conditions, electrical and operating characteristics, pin functions, typical performance graphs, and package information. It also contains the important notice regarding warranty, usage restrictions, and safety‑critical applications.
