Description

This is a stereo fully digital audio amplifier with

output power which can deliver up to 2×16W to 4Ω

load with 12V supply voltage. Using I²C digital

control interface, AD8256A provides sound

34mW into 32Ω@1kHz and 1% THD+N

65mW into 16Ω@1kHz and 1% THD+N

110mW into 8Ω@1kHz and 1% THD+N

200mW into 4Ω@1kHz and 1% THD+N

z Sound processing including：

processing functions including Volume, Bass, Treble,

EQ, Mixing and Dynamic Range Control (DRC).

Bass (+18dB~-12dB, 3dB frequency is 250Hz),

Treble (+18dB~-12dB, 3dB frequency is 7kHz),

5 bands parametric EQ,

Volume control (+24dB~-103dB, 1dB/step) and
