Low-Voltage, Single Supply, Dual SPST,
SPDT Analog Switches
The Intersil ISL5120, ISL5121, ISL5122, ISL5123 devices are
precision, bidirectional, dual analog switches designed to
operate from a single +2.7V to +12V supply. Targeted
applications include battery powered equipment that benefit
from the devices鈥?low power consumption (5碌W), low leakage
currents (100pA max), and fast switching speeds (t
ON
= 28ns,
t
OFF
= 20ns). Cell phones, for example, often face ASIC
functionality limitations. The number of analog input or GPIO
pins may be limited and digital geometries are not well suited
to analog switch performance. This family of parts may be
used to 鈥渕ux-in鈥?additional functionality while reducing ASIC
design risk. Some of the smallest packages are available,
alleviating board space limitations, and making Intersil鈥檚
newest line of low-voltage switches an ideal solution.
The ISL5120, ISL5121, ISL5122 are dual single-pole/single-
throw (SPST) devices. The ISL5120 has two normally open
(NO) switches; the ISL5121 has two normally closed (NC)
switches; the ISL5122 has one NO and one NC switch and
can be used as an SPDT. The ISL5123 is a committed SPDT,
which is perfect for use in 2-to-1 multiplexer applications.
