The TPA741 is a low voltage single-channel audio power amplifier from TI. It can work with 3.3V and 5V power supply, and has a maximum output power of 700mW. It is suitable for applications with internal speakers.
The TPA741 SLOS316C is a bridge‑tied‑load (BTL) audio power amplifier designed for low‑voltage applications such as battery‑powered equipment. It operates from 2.5 V to 5.5 V and is available in 8‑pin SOIC and PowerPAD™ MSOP packages.
Key features include integrated depop circuitry, shutdown mode with ultra‑low quiescent current, and protection against thermal overload and short‑circuit conditions. The device delivers up to 700 mW peak output (250 mW continuous at 5 V into an 8 Ω load) with THD+N of 0.5 % across the voice band.
