Ordering number :ENN6140A Bi-CMOS IC LV1150 Virtual Surround System IC Overview The LV1150 is a virtual surround system Bi-CMOS IC for video soundtracks and audio. The main feature of this IC is the ability to create an audio ambience equivalent to that of a multichannel system by adding a signal to which virtual surround processing has been applied to the left and right channel input signals. It furthermore allows modification of this effect by the use of L+R and L–R passive matrix processing and adjustment of the surround processing level with a level control. Package Dimensions unit: mm 3067-DIP24S [LV1150] 24 13 7.62 6.4 1 21.
