Sales Briefcase
  • FDA801B 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.
    FDA801B 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 FDA801B is able to work with power supply as low as 6 V, thus supporting the most recent low voltage ('start-stop') car-makers specification.
