DESCRIPTION

The WM8912 is a high performance ultra-low power stereo DAC optimised for portable audio applications.

The device features stereo ground-referenced headphone amplifiers using the Wolfson ‘Class-W’ amplifier techniques - incorporating an innovative dual-mode charge pump architecture - to optimise efficiency and power consumption during playback. The ground-referenced outputs eliminate headphone coupling capacitors. The outputs include common mode feedback paths to reject ground noise.

FEATURES

? 3.8mW quiescent power consumption for DAC to headphone playback

? DAC SNR 96dB typical, THD -86dB typical

? Class W ground-referenced headphone driver

- 28mW per channel into 30Ω at <1 THD

- 32mW per channel into 15Ω at <1 THD

? Dynamic range controller

? ReTune? Mobile parametric equalizer

? Integrated control write sequencer for pop minimised startup and shutdown

? Single register write for default start-up and shutdown sequences

? On-chip FLL provides all necessary clocks

? DAC supports standard sample rates from 8kHz to 96kHz

? 32-pin QFN package (4x4mm, 0.4mm pitch)

APPLICATIONS

? Portable multimedia players

? Multimedia handsets

? Handheld gaming
