FDA801 is a new BCD technology quad BRIDGE class D amplifier, specially intended for automotive applications. Thanks to the technology used, it is possible to integrate a high performance D/A converter together with powerful MOSFET outputs in class D, to get an outstanding efficiency compared with the standard class AB. The integrated D/A converter allows to reach outstanding performances (110 dB S/N ratio with 108 dB of dynamic range). The feedback loop includes the output L-C low-pass filter, allowing superior frequency response linearity and lower distortion independently from the inductor and capacitor quality. FDA801 is fully configurable through I2C bus interface and integrates a full diagnostics array specially intended for automotive applications. Thanks to the solutions implemented to contain EMI emissions, the device is intended to be used in the standard single DIN car-radio box together with the tuner. Moreover FDA801 is able to work with power supply as low as 6 V, thus supporting the most recent low voltage ('start-stop') car-makers specification.

The FDA802AB is a dual bridge class D amplifier, designed in the most advanced BCD technology specially intended for car radio applications. The FDA802AB integrates a high performance D/A converter together with powerful MOSFET outputs in class D, to get an outstanding efficiency compared with the standard class AB. The integrated D/A converter allows to reach outstanding performances (115 dB S/N ratio with 110 dB of dynamic range). Thanks to the high-voltage MOSFET output stages it can operate both under standard car battery (6 -18 V) and under boosted power supply (up to 50 V) to reach the highest possible power with integrated solution.

The FDA803Q is a single bridge class D amplifier, designed in the most advanced BCD technology, intended for any automotive audio application (car radio, telematics and e-call, noise and tone generators, etc). The FDA803Q integrates a high performance D/A converter together with powerful MOSFET outputs in class D, so it is very compact and powerful, moreover it reaches outstanding efficiency performances (90%). It has a very wide operating range: it can be operated both with standard car battery levels (5.5-18 V operating, compatible to load dump pulse) and with external step-down generated voltages or emergency battery (since it is compatible to minimum 3.3 V operative). The feedback loop includes the output L-C low-pass filter, allowing superior frequency response linearity and lower distortion. FDA803Q is configurable through I2C bus interface and integrates a complete diagnostics array specially intended for automotive applications including innovative open load and DC offset detection in play mode. Thanks to the solutions implemented to solve the EMI problems, the device is intended to be used in the standard single DIN car-radio box together with the tuner. Moreover, FDA803Q features a configurable amplitude limiter function, and can be optionally operated under no I2C mode ('legacy mode').

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.
