Product overview

Description

The FDA803S is the new ST single channel class-D audio amplifier, specifically designed for automotive applications. The FDA803S 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 FDA803S supports I2S and TDM digital bit stream up to 16CH with several sampling frequencies from 8 kHz up to 96 kHz. FDA803S embeds a complete diagnostic in play to support the most demanding OEM requirements in terms of speaker control and system robustness/ reliability.

The FDA803S supports start stop cranking down to 3.3 V and it is available in a very compact and thin QFN 5x5 package. Thus the FDA803S is suitable for any level of automotive application especially e-Call and Telematics.
