General introduction

FDA801 is a fully digital single chip class D amplifier with high immunity to the demodulation

filter effects. The high integration level and the on-board signal processing allow excellent

audio performance to be achieved.

Thanks to the digital input and to the feedback strategy in the power stage that make the

amplifier immune from the output filter components non-linearity, the number and size of the

external components are minimized.

A number of features are included to reduce EMI and the fully digital approach provides a

strong GSM immunity.

signal processing for interpolation and noise shaping, innovative self-diagnostic functions

and automatic detection of wrong load connections or variation of the load, internal PLL for

a clock generation.
