Описание

The TAS5760M-Q1 is a stereo digital 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 25 W instantaneous power into 4 Ω at 10% THD+N at 14.4 V. The TAS5760M-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).An optimal mix of thermal performance and device cost is provided in the 120-mΩ RDS(ON) of the output MOSFETs.The device is offered in a thermally enhanced 32-Pin HTSSOP (DAP) package.
