Description
The FDA903S is the new ST single channel class-D audio amplifier, specifically
designed for automotive applications. The FDA903S integrates a 24-bit, 100 dB
DAC conversion and PWM class-D output stage with feedback before LC filter. This
configuration enables the design of a compact and inexpensive application.
The FDA903S supports I2S and TDM digital bit stream up to 16CH with several
sampling frequencies from 8 kHz up to 96 kHz. FDA903S embeds a complete
diagnostic in play, including real-time load-current monitoring and digital admittance
meter, to support the most demanding OEM requirements in terms of speaker control
and system robustness/ reliability.
The FDA903S supports start stop cranking down to 3.3 V and it is available in a very
compact and thin QFN 5x5 package. Thus the FDA903S is suitable for any level of
automotive application especially e-Call and Telematics.
