TAS5706B Descrizione generale

Introducing the TAS5706B, a high-performance stereo digital amplifier with an integrated digital signal processor (DSP), specifically engineered for automotive audio systems with applications extending to portable speakers, soundbars, and home theater systems. Boasting a 48 kHz sample rate, 24-bit resolution, and a dynamic range of 100 dB, this amplifier delivers unparalleled audio fidelity. It can provide up to 20 watts per channel into a 4-ohm load, making it compatible with a broad spectrum of speakers. The integrated DSP offers advanced audio processing capabilities, including parametric equalization, dynamic range control, and speaker protection algorithms, allowing for customized sound tuning to suit various audio sources and speaker configurations. Additionally, the TAS5706B includes a digital audio interface with support for I2S and TDM inputs, as well as I2C control for effortless configuration of the DSP parameters. With built-in protection features like overtemperature, overvoltage, and short-circuit protection, the TAS5706B ensures dependable and secure operation
