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.
