Automotive, 8W, 4.5 to 18V analog-input mono Class-D audio amplifier

The TAS5431-Q1 is a mono

class-D audio amplifier, ideal for use in automotive emergency call (eCall),

telematics, instrument cluster, and infotainment 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.
