Negative Signal Swing, Sub-ohm, Dual
SPDT with Click and Pop Elimination
Single Supply Switch
Features
• Pb-free (RoHS Compliant)
The Intersil ISL54062 device is a low ON-resistance, low
voltage, bidirectional, dual single-pole/double-throw (SPDT)
analog switch. It is designed to operate from a single +1.8V to
+6.5V supply and pass signals that swing down to 6.5V below
the positive supply rail. Targeted applications include battery
powered equipment that benefit from low rON (0.56Ω), low
power consumption (20nA) and fast switching speeds
(tON = 55ns, tOFF = 18ns). The digital inputs are 1.8V
logic-compatible up to a +3V supply. The ISL54062 also
features integrated circuitry to eliminate click and pop noise to
an audio speaker. The ISL54062 is offered in a small form
factor package, alleviating board space limitations. It is
available in a tiny 10 Ld 1.8x1.4mm µTQFN or 10 Ld 3x3mm
TDFN package.
The ISL54062 is a committed dual single-pole/double-throw
(SPDT) that consist of two normally open (NO) and two
normally closed (NC) switches with independent logic control.
This configuration can be used as a dual 2-to-1 multiplexer.

Detailed Description
The ISL54062 is a bi-directional, dual single pole-double
throw (SPDT) analog switch that offers precise switching
from a single 1.8V to 6.5V supply with low ON-resistance
(0.83Ω), high speed operation (tON = 55ns, tOFF = 18ns) and
negative signal swing capability. The device is especially
well suited for portable battery powered equipment due to its
low operating supply voltage (1.8V), low power consumption
(20nA @ 3V), and a tiny 1.8mmx1.4mm µTQFN package or a
3x3 TDFN package. The low ON-resistance and rON flatness
provide very low insertion loss and signal distortion for
applications that require signal switching with minimal
interference by the switch.
Supply Sequencing and Overvoltage Protection
With any CMOS device, proper power supply sequencing is
required to protect the device from excessive input currents
which might permanently damage the IC. The ISL54062
contains ESD protection diodes on each pin of the IC
(see Figure 9). These diodes connect to either a +Ring or
-Ring for ESD protection. To prevent forward biasing the
ESD diodes to the +Ring, V+ must be applied before any
input signals, and the input signal voltages must remain
between recommended operating range.
If these conditions cannot be guaranteed, then precautions
must be implemented to prohibit the current and voltage at
the logic pin and signal pins from exceeding the maximum
ratings of the switch. The following two methods can be used
to provided additional protection to limit the current in the
event that the voltage at a logic pin or switch terminal goes
above the V+ rail.
Logic inputs can be protected by adding a 1kΩ resistor in
series with the logic input (see Figure 9). The resistor limits
9
the input current below the threshold that produces
permanent damage.
This method is not acceptable for the signal path inputs.
Adding a series resistor to the switch input defeats the
purpose of using a low rON switch. Alternatively, connecting
external Schottky diodes from the V+ rail to the signal pins
will shunt the fault current through the Schottky diode
instead of through the internal ESD diodes, thereby
protecting the switch. These Schottky diodes must be sized
to handle the expected fault current.

Power-Supply Considerations
The ISL54062 construction is typical of most single supply
CMOS analog switches which have two supply pins: V+ and
GND. V+ and GND provide the CMOS switch bias and sets
their analog voltage limits. Unlike switches with a 5.5V
maximum supply voltage, the ISL54062’s 6.5V maximum
supply voltage provides plenty of head room for the 10%
tolerance of 5V supplies due to overshoot and noise spikes.

ISL54062
The minimum recommended supply voltage is 1.8V. It is
important to note that the input signal range, switching times,
and ON-resistance degrade at lower supply voltages. Refer
to the “Electrical Specifications” tables, beginning on page 3,
and “Typical Performance Curves”, beginning on page 11,
for details.
V+ and GND also power the internal logic and level shifters.
The level shifters convert the input logic levels to V+ and
GND signals levels to drive the analog switch gate terminals.
A high frequency decoupling capacitor placed as close to the
V+ and GND pin as possible is recommended for proper
operation of the switch. A value of 0.1µF is highly
recommended.
placed on the COM pin. This impedance is small enough to
reduce the voltage build up significantly while not increasing
the power dissipation dramatically. Current consumption
considerations will need to be taken for driving a smaller
load impedance under this scenario.

Click and Pop Operation
The ISL54062 contains circuitry that prevents audible click
and pop noises that may occur when audio sources are
powered on or off. Single supply audio sources are biased at
a DC offset that can generate transients during power on/off.
A DC blocking capacitor is needed to remove the DC bias at
the speaker load. For 32Ω headphones, a 220µF capacitor is
typically used to preserve the audio bandwidth. The power
on/off transients are AC coupled by the 220µF capacitor to
the speaker load causing a click and pop noise.
The ISL54062 has shunt switches on the NO and NC pins to
eliminate click and pop transients (see Figure 10). These
switches are driven complimentary to the main switch. When
NC is connected to COM, the shunt switch is active on the
NO pin (and vice versa). The shunt switches connect an
impedance (140Ω typical, see Figure 24) from the NO/NC
pin to ground to discharge any transients that may appear on
the NO or NC pins.
When a DC bias becomes active at the source, the NO and
NC terminals will also have a DC offset due to capacitor
dv/dt principle. The DC offset will be discharged through the
shunt impedance on the NO and NC terminals instead of the
speaker, eliminating click and pop noise.
*Under high impedance loads such as the input impedance
of pre-amplifiers (20kΩ), the COM terminal voltage may rise
due to small leakage currents charging the COM
capacitance. This is not seen when low impedance loads
such as headphones (32Ω) are used because the small
leakage currents does not result in significant potential drop
across the load. If the user desires to reduce the voltage
build up on the COM pin, a 1kΩ resistor to ground may be

Negative Signal Swing Capability
The ISL54062 contains circuitry that allows the analog
switch signal to swing below ground. The device has an
analog signal range of 6.5V below V+ up to the V+ rail (see
Figure 16) while maintaining low rON performance. For
example, if V+ = 5V, then the analog input signal range is
from -1.5V to +5V. If V+ = 2.7V then the range is from -3.8V
to +2.7V.

Click and Pop Elimination with INx Pin
Audio click and pop elimination can be driven with the Input
Select (INx) pin. When INx = 0, the NOx terminals are
connected to the shunt impedance. When INx = 1, the NCx
terminals are connected to the shunt impedance. In this
situation, only one of the source transient voltages will be
shunted to ground, depending on the Input Select state. The
Input Select pin should be driven 200ms after any source
transients occurs to prevent audible transients at the
speaker load.
Logic-Level Thresholds
This switch family is 1.8V CMOS compatible (0.45V VOLMAX
and 1.35V VOHMIN) over a supply range of 1.8V to 3.3V
(see Figure 18). At 3.3V the VIL level is 0.5V maximum. This
is still below the 1.8V CMOS guaranteed low output
maximum level of 0.45V, but noise margin is reduced to
approximately 50mV. At 3.3V the VIH level is 1.4V minimum.
While this is above the 1.8V CMOS guaranteed high output
minimum of 1.35V, under most operating conditions the
switch will recognize this as a valid logic high.
The digital input stages draw supply current whenever the
digital input voltage is not at one of the supply rails. Driving
the digital input signals from GND to V+ with a fast transition
time minimizes power dissipation. The ISL54062 has been
designed to minimize the supply current whenever the digital
input voltage is not driven to the supply rails (0V to V+). For
example, driving the device with 2.85V logic high while
operating with a 4.2V supply the device draws only 1µA of
current.

High-Frequency Performance
Leakage Considerations
In 50Ω systems, the ISL54062 has an ON switch -3dB
bandwidth of 60MHz (see Figure 21). The frequency
response is very consistent over a wide V+ range, and for
varying analog signal levels.
Reverse ESD protection diodes are internally connected
between each analog-signal pin, V+ and GND. One of these
diodes conducts if any analog signal exceeds the
recommended analog signal range.
An OFF switch acts like a capacitor across the open
terminals and AC couples higher frequencies, resulting in
signal feed-through from a switch’s input to its output.
Off-Isolation is the resistance to this feed-through. Crosstalk
indicates the amount of feed-through from one switch
channel to another switch channel. Figure 22 details the high
Off-Isolation and Crosstalk rejection provided by this part. At
100kHz, Off-Isolation is about 60dB in 50Ω systems,
decreasing approximately 20dB per decade as frequency
increases. At 1MHz, Crosstalk is about -75dB in 50Ω
systems, decreasing approximately 20dB per decade as
frequency increases.
Virtually all the analog switch leakage current comes from the
ESD diodes and reversed biased junctions in the switch cell.
Although the ESD diodes on a given signal pin are identical and
therefore fairly well balanced, they are reverse biased
differently. Each is biased to either the +Ring or -Ring and the
analog input signal. This means their leakages will vary as the
signal varies. The difference in the two diode leakages to the
+Ring or -Ring and the reverse biased junctions at the internal
switch cell constitutes the analog-signal-path leakage
current.
