Description

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.

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.
