  • 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 Ω and 1 Ω 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.
