3 Description

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.
