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, PRO-
Spatializer
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
(V
CC-SP
= 4.2 V, RL = 8
, when AGC is on, the rate of the output wave pattern's distortion would be approximately 1%)
y
Operating supply voltage: V
CC
= 2.55 V to 3.5 V, V
CC-SP
= 2.55 V to 4.5 V
Applications
y
Cellular phones, PDAs and portable DVD players
Package
y
32-pin fine pitch land grid array package (XLGA type)
Type
y
Silicon monolithic bipolar IC
