The TAS5411-Q1 is a mono class-D audio amplifier, ideal for use in automotive emergency call (eCall), telematics, and instrument cluster applications. The device provides up to 8 W into 4 Ω at less than 10% THD+N from a 14.4-Vdc automotive battery. The wide operating voltage range and excellent efficiency make the device 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.
