Overview
Package Dimensions
The LV1035M is a Dolby ProLogic surround signalprocessing IC that combines the functionality of the
LV1016 and LA2786 products. The LV1035M allows
systems that provide both Dolby ProLogic surround
functionality and a wide range of additional digital
surround functions to be constructed with a single IC.
