Description

The FDA802S is a dual bridge class D amplifier, designed in the most advanced BCD

technology specially intended for car radio applications.The FDA802S integrates a

high performance D/A converter together with powerful MOSFET outputs in class D,

to get an outstanding efficiency compared with the standard class AB.

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

ratio with 108 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 25 V) to reach the highest possible power with integrated

solution. The feedback loop includes the output L-C low-pass filter, allowing superior

frequency response linearity and lower distortion independently from the inductor and

capacitor quality.
