TDA7491LP13TR

The TDA7491LP13TR is a dual-channel audio power amplifier IC from STMicroelectronics (TDA7491 family) designed for compact consumer audio. It provides two Bridge-Tied-Load (BTL) outputs that can directly drive speakers from a single supply, offering good efficiency for mid-power stereo applications. The device integrates the output stage and protection features, including short-circuit/overcurrent, overtemperature, undervoltage, and soft-start to reduce turn-on pops. It accepts standard audio inputs and is suitable for devices like TVs, set‑top boxes, soundbars, and portable speakers, with minimal external components (mainly decoupling and input conditioning). The “LP” and “13TR” suffixes indicate a specific package and Tape & Reel packaging. For exact power ratings, supply voltage range, pinout, and layout, consult the datasheet and reference designs.
