Detailed Description

FDA901 is a new BCD technology Quad Bridge class D amplifier, specially intended for car radio 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 to 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).

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.
FDA901 is fully configurable through I²C bus, moreover it includes not only the most complete load diagnostic matrix but also a unique real time load current acquisition on I²C and I²S data lines, enabling sophisticated speaker monitoring functions.
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 the FDA901 is able to work with power supply as low as 6 V, thus supporting the most recent low voltage ('start-stop') car-makers specification.
