TAS5411-Q1 - 8-W Analog Input Mono Automotive Class-D Audio Amplifier With Load Dump, I2C Diagnostics​​

The TAS5411-Q1 is a mono class-D audio amplifier, ideal for use in automotive emergencycall (eCall), telematics, and instrument cluster applications. The device provides up to 8 W into 4Ω at less than 10% THD+N from a 14.4-Vdc automotive battery. The wide operating voltage range andexcellent efficiency make the device ideal for start-stop support or running from a backup batterywhen required. The integrated load-dump protection reduces external voltage clamp cost and size,and the onboard load diagnostics report the status of the speaker throughI²C.
