The FDA903S is the brand new ST single channel class-D audio amplifier providing speaker management and system robustness/ reliability.
STMicroelectronics FDA903S Class-D Automotive Audio Amplifier is particularly designed for automotive purposes, particularly e-Name and telematics. The FDA903S incorporates a 24-bit, 100dB DAC conversion and PWM class-D output stage with suggestions earlier than the LC filter. This configuration can create the design of a compact and cheap utility.
The STM FDA903S Class-D Automotive Audio Amplifier helps I2S and TDM digital bit streams as much as 16CH with a number of sampling frequencies from 8kHz to 96kHz. FDA903S embeds a whole diagnostic in play, together with real-time load-current monitoring and a digital admittance meter, to ship probably the most demanding OEM necessities concerning speaker management and system robustness/ reliability. The FDA903S helps begin cease cranking down to three.3V.
