•
The RS2166 is a bidirectional 1-channel single-pole
single-throw (SPST) analog switch, which is designed
to operate from 1.8V to 5.5V.
The RS2166 device can handle both analog and
digital signals. It features bandwidth(300MHz) and
low on-resistance (4.5Ω TYP).
Each switch section has its own enable-input control
(SEL). A high-level voltage applied to SEL turns on
the associated switch section.
APPLICATIONS
•
Wireless Devices
•
Audio and Video Signal Routing
•
Portable Computing
•
Wearable Devices
•
Signal Gating, Chopping, Modulation or
Demodulation (Modem)
•
Cell Phones
Applications include signal gating, chopping,
modulation or demodulation (modem), and signal
multiplexing for analog-to-digital and digital-to-analog
conversion systems.

(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These
are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied.
(2) All voltages are with respect to ground, unless otherwise specified.
(3) The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

TYPICAL APPLICATION
The RS2166 can be used in any situation where an SPST switch would be used and a solid-state, voltagecontrolled version is preferred. The RS2166 allows on and off control of analog and digital signals with a
digital control signal. All input signals should remain between 0V and VCC for optimal operation.
