Power amplifier system for automotive applications
Get started with ST's FDA801 - Best Car Radio ClassD efficiency on the market - 4x50 W class-D digital input power amplifier with I2C diagnostics and low voltage operation
New single-channel Class-D amplifiers with unique diagnostic matrix ensures high-end audio performance
Featuring advanced diagnostics, high efficiency and a unique load current monitor feature 
to ensure high system reliability, FDA803D and FDA903D are the latest amplifiers in our FDA80x family of automotive Class-D audio power amplifiers.
Thanks to an innovative architecture that includes a low-pass output filter in the feedback loop, these devices offer high-quality sound at a reduced system cost. Moreover, supporting a very wide supply voltage range (from 3.3 to 18 V) they are the best fit for any automotive audio application including standard car audio systems to today's e-call and acoustic vehicle alerting systems (AVAS).
