Package: TSSOP 16 Pin Type

Manufacturer: Texas Instruments


TAS5421-Q1 datasheet



The TAS5421-Q1 is a mono digital audio amplifier, ideal for use in automotive emergency call (eCall), telematics, instrument cluster, and infotainment applications. The device provides up to 22 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.
