The CS48DV2 processor gives OEMs a cost effective, fixed-function, simple-to-design Dolby Volume 2.0 to 2.1 channel solution. Designed to provide high-performance volume control using the Dolby Volume algorithm, the low-power standby of the CS48DV2 DSP Family preserves battery life for applications which are always on, but not necessarily processing audio, such as portable audio systems.
