ISL54006 Typical Application Circuit and Block Diagram
Detailed Description
The Intersil ISL54003, ISL54005, and ISL54006 family of
devices are integrated audio power amplifier systems
designed to provide quality audio, while requiring minimal
external components. The low 0.4% THD+N ensures clean,
low distortion amplification of the audio signals. The devices
are designed to operate from a single +2.7V to +5V power
supply. All devices are offered in a 20 Ld 4x4 TQFN package.
Targeted applications include battery powered equipment
such as cell-phones, MP3 players, and games/toys.
These parts contain one class AB BTL type power amplifier
for driving an 8
Ω mono speaker and two class AB
single-ended (SE) type amplifiers for driving 16
Ω or 32Ω
headphones.
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. When the speaker load is connected across the
positive and negative terminals of the BTL driver the voltage
is doubled across the load and the power is quadrupled.
Each SE amplifier when using a 5V supply is capable of
delivering 15mW (typ) with 0.07% THD+N and 50mW (typ)
with 0.3% THD+N of continuous average power into a 32
Ω
headphone speaker.
When in Mono Mode (BTL driver active) 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.
The ISL54005 and ISL54006 feature a 2:1 stereo input
multiplexer front-end. This allows selection between two
stereo sources. The INS control pin determines which stereo
input is active. Applying logic “0” to the INS control pin
selects stereo input 1 (R1 and L1). Applying logic “1” to the
INS control pin selects stereo input 2 (R2 and L2).
The ISL54006 has the capablity of mixing the two stereo
inputs. When in MIX Mode and HEADPHONE Mode, the
part mixes the R1 input with the R2 input and sends the
combined signal to the HpR headphone driver and it mixes
the L1 input with the L2 input and sends the combined signal
to the HpL headphone driver. When in MIX Mode and
MONO Mode, it mixes all four inputs (R1 + R2 + L1 + L2) and
sends the combined signal to the BTL mono driver.
These parts have headphone sense input 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 (HO) that can override the sense
input circuitry.
