The E-TDA7391PDTR is a digitally controlled audio processor from STMicroelectronics. It is an audio amplifier which offers superior sound quality and clear, dynamic sound reproduction. It features a dual-channel input CMOS differential amplifier, which helps reduce input noise and distortion. It also includes an 8-bit-resolution digital-to-analog converter (DAC) for low-noise output in 2.0-channel stereo mode and digital input compatibility with I2S and SPDIF signals. Its high-performance post-processing processing algorithms support low distortion, low noise, low cross-talk, and excellent headroom. It is suitable for a variety of audio applications such as automotive entertainment systems, home theater, media players, public address systems, and gaming.
