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 configuration, to get 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). The feedback loop is including 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.
