Integrated Audio Amplifier Systems
The Intersil ISL54000, ISL54001, ISL54002 family of devices
are integrated audio power amplifier systems that combine
stereo BTL 8Ω amplifiers in a single package. The devices are
designed to operate from a single +2.7V to +5V power supply.
All devices are offered in a 20 Ld 4x4 thin QFN package.
Targeted applications include handheld equipment such as
cell-phones, MP3 players, and games/toys.
The ISL54000, ISL54001, ISL54002 parts contain two class
AB bridge-tied (BTL) type power amplifiers for driving stereo
8Ω speakers. Each BTL is capable of delivering 800mW (typ)
with 0.4% THD+N and 941mW (typ) with 1% THD+N of
continuous average power into an 8Ω BTL speaker load
when using a 5V supply.
The ISL54001 and ISL54002 feature a 2:1 stereo input
multiplexer front-end. This allows selection between two
stereo sources. In addition the ISL54002 has the capability
of mixing the stereo inputs.
All devices in this family feature low power shutdown,
thermal overload protection and click/pop suppression. The
click and pop circuitry eliminates audible transients during
audio source changes and transitioning in and out of
shutdown.
