+1.8V to +6.5V, Sub-Ohm, Dual SPDT
Analog Switch with Negative Signal
www.dCataasphaeebt4iuli.ctoymand Click and Pop Elimination
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 up 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 are1.8V
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.

High-Frequency Performance
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.
An OFF switch acts like a capacitor across the open
www.tdeartmasihneaelst4aun.cdomAC 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.
Leakage Considerations
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.
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.
