Integrated Audio Amplifier Systems

Features

The Intersil ISL54003, ISL54005, ISL54006 family of devices

are integrated audio power amplifier systems that combine a

mono BTL amplifier and stereo headphone amplifiers in a

single device. The devices are designed to operate from a

single +2.7V to +5V power supply. Targeted applications

include handheld equipment such as cell-phones, MP3

players, and games/toys.

• Pb-Free (RoHS Compliant)

• Class AB 94mW Headphone Amplifiers and 941mW Mono

BTL Speaker Amplifier

• THD+N at 1kHz, 800mW into 8Ω BTL. . . . . . . . . . . . . . 0.4%

• THD+N at 1kHz, 15mW into 32Ω Headphone . . . . . . 0.07%

• THD+N at 1kHz, 50mW into 32Ω Headphone . . . . . . . 0.3%

• Single Supply Operation. . . . . . . . . . . . . . . . . +2.7V to +5.5V

• Headphone Sense Input and Low Power Shutdown

• Thermal Shutdown Protection

These parts contain 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.

• “Click and Pop” Suppression Circuitry

• 2:1 Stereo Input Mux (ISL54005, ISL54006)

• Mixing of Two Stereo Inputs (ISL54006)

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.

• TTL Logic-Compatible

• Available in 20 Ld 4x4 Thin QFN

Applications

When in Mono Mode these devices automatically mix the

active left and right audio inputs and send 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.

• Battery powered, Handheld, and Portable Equipment

- Cellular/mobile Phones

- PDA’s, MP3 Players, DVD Players, Cameras

- Laptops, Notebooks, Palmtops

The ISL54005 and ISL54006 feature a 2:1 stereo input

multiplexer front-end. This allows selection between two

stereo sources. In addition the ISL54006 can mix the four

inputs to the BTL driver or the two pairs of inputs to the

headphone drivers.

- Handheld Games and Toys

• Desktop Computers

Simplified Block Diagram

These parts feature headphone sense circuitry that detects

when a headphone jack has been inserted and automatically

switches the active audio inputs from the mono BTL output

driver to the headphone drivers. These parts also feature a

logic control pin that can override the headphone sense

input circuitry.

ROUTER/

MIXER

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.
