描述

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.
