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.

FDA802SB 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 the

FDA802SB 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.
