The FDA802 is a dual bridge class D amplifier, designed in the most advanced BCD technology specially intended for car radio applications.
The FDA802 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.
FDA802 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 FDA802 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.主な特徴
