This is an analog IC virtual surround processor that faithfully reproduces the sound algorithm developed by Q SOUND Labs, Inc.
In particular, when a stereo signal (L/Rch) encoded by Dolby Pro Logic is input to this IC, a virtual rear speaker is created spatially, and this allows reproduction of realistic, 3-dimensional sound from two speakers, without the addition of another speaker.
Q Xpander technology allows deep, spatially wide sound for input of normal stereo signals, as well.
* Virtual Dolby sound is a system developed by Dolby Labs, Inc. that reproduces realistic Pro Logic sound with just two front left and right speakers, so there is no need for the additional two rear speakers and center speaker normally required for Pro Logic sound.
* Dolby and Dolby Surround are registered trademarks of Dolby Laboratory Licensing Corporation.
* The Q Surround virtual processor (MM1454) was developed by Mitsumi Electric, and has not received the certification or authorization of Dolby Laboratory.
* Mitsumi Electric has no business ties or other relationship with Dolby Laboratory.

Features
*Virtual rear speakers allow reproduction of 3-dimensional sound through only two speakers when a Pro Logic encoded source is input.
*Also reproduces wide sound for a normal stereo source.
*2ch input - 2ch output.
*Few external parts due to use of the active filter created using Mitsumi's bipolar technology.
*Low noise design Q Surround ON: 15μVrms, OFF: 10μVrms
*Simple structure results in small size and low cost.

Applications
*TV, VCR
*Audio equipment
*Computer monitors
*Active speaker systems

These ICs were developed for STATIC-RAM (S-RAM) battery back-up, and have built-in switching circuit for main power supply and battery, back-up timing circuit and battery checker.
Power ON/OFF and momentary power interruptions can damage S-RAM data on equipment that contains an S-RAM. These ICs switch the S-RAM to back-up mode (CS signal makes S-RAM CE pin low and CE pin high)
when power supply voltage goes below a set voltage (detection voltage 4.2V typ., variable), preventing damage to data. Further, when power supply voltage drops, these ICs switch from main power supply to battery back-up (switching voltage 3.3V typ.). Then, when power supply voltage rises, they first switch the SRAM from battery back-up state to main power supply (switching voltage 3.3V typ.), and from back-up mode to normal mode (CS signal makes S-RAM CE pin high and CE pin low). These signal processes provide reliable protection against data damage. The CS signal also can absorb power supply chattering and roughness through the external capacitor.
There is a built-in battery checker to monitor the back-up battery voltage, and this circuit is turned ON/OFF by the control pin.

Features
*Battery back-up

-External transistor drive current (for output current increase) 25mA typ.
