Product overview
Description
The FDA902HP is a dual bridge class-D amplifier, designed in the most advanced BCD technology expressly intended for car radio applications.
The FDA902HP 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 amplifiers.
Thanks to the high-voltage MOSFET output stages it can operate both under standard car battery (6–18 V) and under boosted power supplies (up to 40 V) to deliver the highest possible power with an integrated solution.
The feedback loop includes the output LC low-pass filter, allowing superior frequency response linearity and lower distortion independently from the inductor and quality of the inductors and capacitors.
The FDA902HP is fully configurable through I²C bus interface and integrates a complete diagnostics array especially intended for automotive applications.
Thanks to the solutions implemented to solve EMI problems, the device is intended to be used in a standard single DIN car-radio enclosure, even when equipped with a tuner.
Moreover, FDA902HP is able to operate with a power supply as low as 5.5 V, thus supporting the most recent low voltage levels specified by car-makers (for example, for 'start-stop' compatibility).
