The FDA450LV is a new BCD- SOI (silicon on insulation) technology QUAD BRIDGE class D amplifier, specially intended for car radio 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 of the inductor and capacitor quality.FDA450LV is fully configurable through I²C bus interface and integrates a full diagnostics array specially intended for automotive applications.Thanks to the solutions implemented to solve the EMI problems, the device is conceived to be used in the standard single DIN car-radio box together with the tuner.The possibility to parallelize the outputs allows to drive both 2 O and 1 O speakers.Moreover FDA450LV is able to work with power supply as low as 6 V, thus supporting the most recent low voltage ("start-stop") car-makers specification.
