DESCRIPTION
The WM8608 comprises a high performance multi-channel PWM digital power amplifier controller. Simply by adding appropriate power output stages a multi-channel power amplifier may be built. Six identical full audio bandwidth channels, plus a reduced bandwidth sub channel are provided as PWM outputs, to drive 6 speakers plus Sub.

FEATURES
• Multi-channel PWM audio amplifier controller
