SLOS751D March 2013 – November 2018 DRV2667
If the user leaves the state of the DAC at any level other than mid-scale (0x00), the DAC automatically ramps down at a safe rate after the timeout period has expired. If the DRV2667 device is properly programmed, the ramp down sequence will never be used. This is a failsafe for any unavoidable interruptions to the playback process. Any writes to the FIFO during the ramp down period are discarded.
