AD8258A Product details

Description
This is a stereo/mono fully digital audio amplifier with output power which can drive 8Ω/4Ω load with up to 24 V voltage supply. Using I2C digital control interface, AD8258A provides sound processing includes Volume, Bass, Treble, EQ, Mixing and Dynamic Range Control (DRC). Protection circuits are provided to protect AD8258A damage while connection error. It is possible to compose of 2.1 channels with two pieces of AD8258A and 5.1 channels with four pieces.
