The Spatializer environ is Desper Products, Inc.'s exclusive signal processing technology that is able to generate surround sound for low-power mobile applications. The technology is based on the company’s commercial 3D audio production system, PROSpatializer Audio Production System. The AN12974A IC employs the same innovative technology of the PRO-Spatializer Audio Production System to enhance sound for products with close proximity speakers such as those on headphones and cellular phones to expand the soundfield for a much more spacious sound. Features y Delivers spacious 3D sound for a stereo system with such as cellular phones' speakers in close proximity. y The AGC circuitry can activate to minimize distortion, raising the average volume level and it can prevent speaker from breaking when an input level is too high. y High output BTL power amplifier, when AGC is on, speaker output: 700mW (VCC-SP = 4.2 V, RL = 8 Ω, when AGC is on, the rate of the output wave pattern's distortion would be approximately 1%) y Operating supply voltage: VCC = 2.55 V to 3.5 V, VCC-SP = 2.55 V to 4.5 V Applications y Cellular phones, PDAs and portable DVD players Spatializer environ provides a dramatic, surround sound effect with just two speakers Speaker Speaker 1 2 3 4 5 6 7 8 9 * 0 # Portable DVD Player Package y 32-pin fine pitch land grid array package (XLGA type) Type y Silicon monolithic bipolar IC Note) Spatializer and the circle-in-square device trademark are owned by Desper Products, Inc.

and negative phase speaker output pins (pin 10, pin 13) have the possibility of break-down caused by the power line short and the ground short.

(2) The technical information described in this material is limited to showing representative characteristics and applied circuits examples of the products. It neither warrants non-infringement of intellectual property right or any other rights owned by our company or a third party, nor grants any license. (3) We are not liable for the infringement of rights owned by a third party arising out of the use of the technical information as described in this material. (4) The products described in this material are intended to be used for standard applications or general electronic equipment (such as office equipment, communications equipment, measuring instruments 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. (5) The products and product specifications described in this material are subject to change without notice for modification and/or improvement. At the final stage of your design, purchasing, 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. (6) When designing your equipment, comply with the guaranteed values, in particular those of maximum rating, the range of operating power supply voltage, and heat radiation characteristics. Otherwise, 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, take into the consideration of incidence of break down and failure mode, possible to occur to semiconductor products. Measures on the systems such as redundant design, arresting the spread of fire or preventing glitch are recommended in order to prevent physical injury, fire, social damages, for example, by using the products. (7) When using products for which damp-proof packing is required, observe the conditions (including shelf life and amount of time let standing of unsealed items) agreed upon when specification sheets are individually exchanged.
