TAS6424L-Q1 Class-D Audio Amplifier Texas Instruments TAS6424L-Q1 Class-D Audio Amplifier is a four-channel digital-input Class-D audio amplifier designed for use in automotive head units and external amplifier modules. The device provides four channels at 27W into 4Ω at 10% Total Harmonic Distortion plus Noise (THD+N) and 27W into 2Ω at 10% THD+N from a 14.4V supply. The Class-D topology dramatically improves efficiency over traditional linear amplifier solutions. The output switching frequency can be set either above the AM band, which eliminates the AM-band interference and reduces output filtering and cost, or below AM band to optimize efficiency. The wide supply-voltage range from 4.5V to 18V helps minimize audio artifacts in start-stop applications. The TAS6424L-Q1 devices are AEC-Q100 qualified for automotive applications.
