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 8Ω mono speaker and two class AB

headphone amplifiers for driving 16Ω 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 8Ω 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 32Ω

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.
