Description

The FDA802B is a dual bridge class D amplifier, designed in the most advanced BCD

technology specially intended for car radio applications.

The FDA802B integrates a high performance D/A converter together with powerful

MOSFET outputs in class D, to get an outstanding efficiency compared to the standard

class AB.

The integrated D/A converter allows to reach outstanding performances (110 dB S/N ratio

with 110 dB of dynamic range).

Thanks to the high-voltage MOSFET output stages it can operate both under standard car

battery (6-18 V) and under boosted power supply (up to 50 V) to reach the highest possible

power with integrated solution.

The feedback loop is including the output L-C low-pass filter, allowing superior frequency

response linearity and lower distortion independently from the inductor and capacitor quality.

FDA802B is fully configurable through I2C bus interface and integrates a complete

diagnostics array specially intended for automotive applications.

Thanks to the solutions implemented to solve the EMI problems, the device is intended to

be used in the standard single DIN car-radio box together with the tuner.

Moreover FDA802B is able to work with power supply as low as 5.5 V, thus supporting the

most recent low voltage ('start-stop') car-makers specification.

The device provides a breakthrough innovative digital impedance-meter which is able to

communicate via I2C the output load value.
