TAS5720A-Q1 1x25-W Digital Input Closed-Loop Automotive Class-D Audio Amplifier - TAS5720A-Q1
 

Description

The TAS5720A-Q1 is a mono I2S input Class-D audio amplifier which is ideal for use in automotive emergency call (eCall), telematics, acoustic vehicle alerting system (AVAS) and EV/HEV sound generation applications. The device provides up to 25W instantaneous power into 4 Ω at 10% THD+N at 14.4 V. The TAS5720A-Q1 also includes hardware and software (I²C) control modes, an integrated digital clipper, selectable gain options, and a wide power supply operating range (4.5 V – 26.4 V).

The device is offered in a thermally enhanced 32-Pin TSSOP package.
