Description

12V~18V for loudspeaker driver

This is a stereo (8Ω)/mono (4Ω) fully digital audio

amplifier with output power which can drive up to

2x10W for stereo or 1x20W for mono at 18V supply

voltage, no external heat-sink or fan is requirement.

Using I²C digital control interface, AD82571A provides

sound processing includes Volume, Bass, Treble, EQ,

Mixing and Dynamic Range Control (DRC). Protection

circuits are provided to protect AD82571A damage

while connection error. It is possible to compose of 2.1

channels with two pieces of AD82571A and 5.1

channels with four pieces.

3.0~3.3V for others

z Loudspeaker output power for 18V

2×10W into 8Ω@0.2% THD+N for stereo

1×20W into 4Ω@0.3% THD+N for mono

z Headphone power

40mW into 32Ω@1kHz and 1% THD+N

80mW into 16Ω@1kHz and 1% THD+N

z Sound processing including：

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

Dynamic range control
