AN12974A
Stereo power amplifier with built-in AGC circuitry and SPATIALIZER
„ Overview
The AN12974A audio power amplifier features built-in AGC circuitry and Spatializer environ.
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

y The power timing of VCC and VCC-SP
This IC have not a standup and falling order in VCC and VCC-SP.
y Pin 6: AGC on/off switch terminal
In order to reduce current consumption during SP-save or standby, when SP-save switch is on (when pin 9 is low-level), also set
pin 6 to low-level.
(When standby switch is on (pin 16 is low-level), SP-save switch will be on.)
y Pin 32: 3D surround spatializer on/off switch
In order to reduce current consumption during standby, when standby switch is on (pin 16 is low-level), also set pin 32 to lowlevel.

y Amplifier output wave pattern
Achieving a big sound volume without clipping distortion by small speakers.
Without AGC
Average sound volume cannot be big without AGC
(wave patters clips when input signal is big and
sound distortion occurs)
With AGC function
Average sound volume can be big with AGC (AGC
prevents sound distortion when input signal is big)
Record output wave patterns by inputting same signals with 2 amplifiers.

„ Usage Notes
y Avoid the power line short and the ground short of the terminals.
y Especially positive phase speaker output pins (pin 12, pin 15) 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.
Be sure to avoid power line short, ground short and load short.

Request for your special attention and precautions in using the technical information
and semiconductors described in this material
(1) An export permit needs to be obtained from the competent authorities of the Japanese Government if any of
the products or technical information described in this material and controlled under the "Foreign Exchange
and Foreign Trade Law" is to be exported or taken out of Japan.
(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.
