Overview
The TAS5720A-Q1 is a 1x25-W digital input closed-loop automotive Class-D audio amplifier produced by Texas Instruments. This device is specifically designed for use in automotive applications, including emergency call (eCall), telematics, acoustic vehicle alerting system (AVAS), and EV/HEV sound generation. It features a mono I²S input and operates within a wide power supply range of 4.5 V to 26.4 V. The amplifier provides up to 25 W instantaneous power into 4 Ω at 10% THD+N at 14.4 V and includes both hardware and software (I²C) control modes.
