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. https://elecena.pl/product/21688426/fda903s-6dy-1-x-10-w-class-d-digital-input-automotive-power-amplifier-with-diagnostics-wide-voltage-operation-range-for-car-aud 2022-09-21 https://elecena.pl/product/21688426/fda903s-6dy-1-x-10-w-class-d-digital-input-automotive-power-amplifier-with-diagnostics-wide-voltage-operation-range-for-car-aud 2024-04-20 https://elecena.pl/product/21688426/fda903s-6dy-1-x-10-w-class-d-digital-input-automotive-power-amplifier-with-diagnostics-wide-voltage-operation-range-for-car-aud 2024-06-20 https://elecena.pl/product/21688426/fda903s-6dy-1-x-10-w-class-d-digital-input-automotive-power-amplifier-with-diagnostics-wide-voltage-operation-range-for-car-aud 2024-07-17 https://elecena.pl/product/21688426/fda903s-6dy-1-x-10-w-class-d-digital-input-automotive-power-amplifier-with-diagnostics-wide-voltage-operation-range-for-car-aud 2024-08-03 https://elecena.pl/product/21688426/fda903s-6dy-1-x-10-w-class-d-digital-input-automotive-power-amplifier-with-diagnostics-wide-voltage-operation-range-for-car-aud 2024-11-16 https://elecena.pl/product/21688426/fda903s-6dy-1-x-10-w-class-d-digital-input-automotive-power-amplifier-with-diagnostics-wide-voltage-operation-range-for-car-aud 2025-07-09
