Car dashboard buzzer device reference design

TIDA-00277

Overview

This TI reference design is a 3.1W mono fully differential audio power amplifier for driving chimes as part of a complete automotive dashboard system solution optimized for the mid-range dashboard market. The entire dashboard solution supports 4.5-40V system functionality and can withstand cold crank, start-stop and load dump conditions.

characteristic

● Common-mode noise-cancelling 3.1W mono fully differential Class AB audio amplifier designed to drive speakers with an impedance of at least 3Ω
● The TPA6211A1-Q1 amplifier requires only three external components (no input coupling capacitors), reducing overall external component count
