Semiconductors\Audio ICs\Audio AmplifiersTAS6422-Q1 2-Channel Class-D Audio Amplifier Texas Instruments TAS6422-Q1 2-Channel Digital-Input Class-D Audio Amplifier is designed for use in automotive head units and external amplifier modules. The device provides two channels at 27W into 4Ω at 10% THD+N and 45W into 2Ω at 10% THD+N from a 14.4V supply. The amplifier can also provide 75W into 4Ω at 10% THD+N from a 25V supply. The Class-D topology dramatically improves efficiency over traditional linear amplifier solutions. The output switching frequency can be set to either above the AM band, which eliminates the AM-band interference and reduces output filtering and cost, or to below AM band to optimize efficiency. The wide supply-voltage range from 4.5V to 26.4V helps minimize audio artifacts in start-stop applications.
