Description
The FDA4100LV 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.
FDA4100LV is fully configurable through I2C bus
interface and integrates a full diagnostics array
specially intended for automotive applications
(with the status of each single speaker).
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.
A built-in step-up driver allows to provide high
output power even using the standard 14 V
supply voltage.
Moreover FDA4100LV is able to work down to 6 V
supply, thus supporting the most recent low
voltage ('start-stop') car-makers specification.
