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.
