Wolfson Microelectronics' WM9081<br />
combines a mono audio DAC and<br />
speaker ampli€er in a single<br />
chip featured to optimise the<br />
sound quality, intelligibility<br />
and noise performance<br />
from low-cost speakers<br />
in space-constrained<br />
portable applications.<br />
<br />
The 2.6W switchable Class-AB/D ampli“er<br />
achieves up to 92dB SNR with low distortion,<br />
and works with the on-chip 24-bit2SI DAC to<br />
deliver exceptional audio performance.<br />
Integrating these two functions saves around<br />
