Description
The FDA2100BLV is a new BCD technology dual
bridge class D amplifier, specially intended for car
radio applications.
Thanks to the BCD6-SOI (Silicon On Insulation)
technology it is possible to integrate a high
performance D/A converter together with powerful
MOSFET output amplifier working in class D, to
get an outstanding efficiency with respect to the
standard class AB.
The D/A conversion on board allows the
performance to reach an outstanding 110 dB S/N
ratio with 105 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.
A full diagnostics array communicates the status
of each speaker through the I2C bus. The
possibility to control the device by means of the
I2C bus makes FDA2100BLV very flexible.
Thanks to the solutions implemented to solve the
EMI problems, the device can be used in the
standard single DIN car-radio box together with
the tuner.
A built-in step-up driver allows up to 150 W output
power with the standard 14 V supply voltage.
The FDA2100BLV is moreover compliant to the
most recent OEM specifications for low voltage
operation (so called 'start-stop' battery profile
during engine stop), helping car manufacturers to
reduce the overall emissions and thus
contributing to environment protection.
