FDA801 4 x 50 W class-D digital input power amplifier with I2C diagnostics and low voltage operation
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, 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.
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.
