Spatializer sound processor IC
I Overview
Unit: mm
10.09 0.ꢀ0
A spatializer audio processor is the Desper Inc.'s
proprietary signal processing technology exclusively
developed for the consumer electronics and multi-
media market. It is based on the Desper's profes-
sional 3D audio production system "PRO-
Spatializer". You can enjoy a sound enhancement and
extension effect with the conventional two-speaker
stereo system by using the innovative technology
adopted in this equipment.

• Fewer external parts (minimum parts count: 4)
• Wide operating supply voltage: 4.5 V to 10 V
• A sound source in the center position is necessarily
positioned in center regardless of the spatializer
effect value.

I Conceptual Description on Spatializer Operation
• Stereo normal mode
All sound are heard from between both left and right
speakers.
• Conventional surround system
Sound expands outside the speakers but the sound
position is not stable.
• Spatializer
The sound expands outside the two speakers and
the sound position is stable.
The sound come to have its expansion and depth.
And also, a sound source in the center position is
necessarily positioned in center regardless of the
spatializer effect value.
I Usage Notes
1. Do not apply 0.3 V or more to pin 12 because it relates with pin 13 (VCC pin)
2. If more than 0.3 V is applied to pin 12, the current flows to pin 13 (VCC pin) via a surge protection diode connected
to pin 12.

(2) The technical information described in this material is limited to showing representative character-
istics and applied circuit examples of the products. It does not constitute the warranting of industrial
property, the granting of relative rights, or the granting of any license.
(3) The products described in this material are intended to be used for standard applications or gen-
eral electronic equipment (such as office equipment, communications equipment, measuring in-
struments and household appliances).
Consult our sales staff in advance for information on the following applications:
• Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment,
combustion equipment, life support systems and safety devices) in which exceptional quality and
reliability are required, or if the failure or malfunction of the products may directly jeopardize life or
harm the human body.
• Any applications other than the standard applications intended.
(4) The products and product specifications described in this material are subject to change without
notice for reasons of modification and/or improvement. At the final stage of your design, purchas-
ing, or use of the products, therefore, ask for the most up-to-date Product Standards in advance to
make sure that the latest specifications satisfy your requirements.
(5) When designing your equipment, comply with the guaranteed values, in particular those of maxi-
mum rating, the range of operating power supply voltage and heat radiation characteristics. Other-
wise, we will not be liable for any defect which may arise later in your equipment.
Even when the products are used within the guaranteed values, redundant design is recommended,
so that such equipment may not violate relevant laws or regulations because of the function of our
products.
(6) When using products for which dry packing is required, observe the conditions (including shelf life
and after-unpacking standby time) agreed upon when specification sheets are individually exchanged.
(7) No part of this material may be reprinted or reproduced by any means without written permission
from our company.
