ISL54004
Integrated Audio Amplifier Systems
The Intersil ISL54004 device is an integrated audio power
amplifier system that combines a mono BTL amplifier and
stereo headphone amplifiers in a single device. It can operate
from a single +2.7V to +5V power supply and is offered in a
20 Ld 4x4 TQFN package. Targeted applications include
handheld equipment such as cell-phones, MP3 players, and
games/toys.
The ISL54004 part contains one class AB BTL type power
amplifier for driving an 8
Ω mono speaker and two class AB
headphone amplifiers for driving 16
Ω or 32Ω headphone
speakers.
The BTL when using a 5V supply is capable of delivering
800mW (typ) with 0.4% THD+N and 941mW (typ) with 1%
THD+N of continuous average power into an 8
Ω BTL speaker
load.
Each headphone amplifier when using a 5V supply is capable
of delivering 50mW (typ) with 0.3% THD+N and 94mW (typ)
with 1% THD+N of continuous average power into a 32
Ω
headphone speaker.
When in Mono mode the part automatically mixes the left and
right audio inputs and sends the combined signal to the BTL
driver. In Headphone Mode, the active right channel input is
sent to the right headphone speaker and the active left
channel is sent to the left headphone speaker.
The ISL54004 has a four-level programmable gain stage to
boost the audio signal. The part requires no external gain
setting resistors.
The ISL54004 part features headphone sense input circuitry
that detects when a headphone jack has been inserted and
automatically switches the audio inputs from the mono BTL
output driver to the headphone drivers. The part also has a
logic control pin that can override the headphone sense
input circuitry.
The part also features low power shutdown, thermal
overload protection and click and pop suppression. The click
and pop circuitry prevents click and pops at the speakers
when transitioning in and out of shutdown.
