TAS5441-Q1 Mono Class-D Audio Amplifier Texas Instruments TAS5441-Q1 Mono Class-D Audio Amplifier is ideal for use in automotive emergency call (eCall), telematics, instrument cluster, and infotainment applications. The device provides up to 22W into 4Ω at less than 10% THD+N from a 14.4VDC automotive battery. The Texas Instruments TAS5441-Q1 has a wide operating voltage range and excellent efficiency which makes it ideal for start-stop support or running from a backup battery when required. The integrated load-dump protection reduces external voltage clamp cost and size, and the onboard load diagnostics report the status of the speaker through I2C.
