| Ordering number : EN5889 Monolithic Linear IC LV1041M Dolby Prologic Decoder Overview The LV1041M is a Dolby Prologic Surround signalprocessing IC that implements in a single chip the functions of the Sanyo LV1016 and LA2786 ICs and a master volume control for the center and surround channels. This IC allows both systems of Dolby Prologic surround and digital surround to be formed into a single IC. Note *: Dolby and the double D symbol are registered trademarks of the Dolby Laboratories Licensing Corporation. This IC can only be used by Dolby licensees. Licensing information and corresponding technical information is available from:Dolby Licensing Corporation San Francisco, CA 94103-4813 USA Features * Implements a Prologic surround decoder in a single chip. * Wide dynamic range * All modes can be controlled from control data transmitted serially over four lines: CLOCK, DATA, ENABLE, and ENABLE2. This function is compatible with the LV1016 and the LA2786.
