This datasheet provides detailed information about the TPA731 audio power amplifier, including its power supply, output power, and packaging.
The TPA731 audio power amplifier is designed for low‑voltage applications that require internal speakers. It operates from a 3.3 V supply to deliver 250 mW continuous power into an 8 Ω BTL load, and up to 700 mW at a 5 V supply. The bridge‑tied load configuration eliminates the need for external coupling capacitors, making it suitable for compact, battery‑powered devices.
The device is offered in an 8‑pin SOIC package and a PowerPAD MSOP package, both surface‑mount. It features a shutdown mode with a 1.5 nA supply current, thermal and short‑circuit protection, and operates over a temperature range of –40 °C to 85 °C. Detailed electrical characteristics, typical performance graphs, and absolute‑maximum ratings are provided in the datasheet.
