Overview

The LV1150M 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.

Functions and Features

• Virtual surround function

• Passive matrix: L+R, L–R

• Adjustable surround effect level

• Bypass and virtual surround (L+R, L–R) switching
function

• Output filters are provided on chip.

• On-chip VDDcircuit

• ADM technique based A/D and D/A converters

• Simulated stereo for monaural input signals

• Package: MFP24 (375-mil lead pitch)
