Description
This is a 2.1-channel fully digital audio amplifier with
output power which can deliver up to 2×8.7W to 8Ω
load for L,R channel and 16.7W to 4Ω load for
sub-woofer channel simultaneously with 12V supply
voltage. Using I
2
C digital control interface, AD8356A
provides sound processing includes Volume, Bass,
Treble, EQ, Mixing and Dynamic Range Control (DRC).
Users can use one AD8356A for stereo or 2.1-channel,
two for 5.1-channel and three for 7.1-channel,
respectively.
