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
