TAS5711 is a 20W digital audio power amplifier with EQ, DRC, and 2.1 mode. It can deliver 20W into an 8Ω load from an 18V supply with up to 90% efficiency. The amplifier operates in Class-D, eliminating the need for heatsinks. It has a signal-to-noise ratio of 106dB and supports speaker equalization and dynamic range compression. The amplifier supports various audio input/output modes and can be used in applications such as televisions, iPod™ Docks, and sound bars.
The TAS5711 is a 20‑W, class‑D digital audio power amplifier designed for stereo bridge‑tied speaker applications. It accepts a single serial audio input and supports up to two discrete audio channels, offering built‑in speaker EQ, dynamic range compression and 3‑D effects. The device operates from a wide PVDD supply range (8 V‑26 V) and requires only 3.3 V for its digital core.
Key features include up to 90 % efficiency, 106 dB A‑weighted signal‑to‑noise ratio, 21 programmable biquad filters, and automatic sample‑rate detection from 8 kHz to 48 kHz. The datasheet provides detailed pin assignments, absolute maximum ratings, recommended operating conditions, and layout guidelines for the 7 mm × 7 mm HTQFP package.
