FDA2100BLV:2x180 W / 1x300 W 35V low voltage operation PWM digital input power amplifier with I2C diagnostics and step-up driver

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.
