Description

FDA901 is a new BCD technology Quad Bridge class D amplifier, specially intended

for car radio automotive applications.

Thanks to the technology used, it is possible to integrate 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 (115 dB S/N

ratio with 110 dB of dynamic range). 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.

complete load diagnostic matrix but also a unique real time load current acquisition

Thanks to the solutions implemented to contain EMI emissions, the device is

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