Low-Voltage, Single Supply, Single SPDT
Analog Switch
The Intersil ISL43210 device is a precision, bidirectional,
single SPDT analog switch designed to operate from a single
+2.7V to +12V supply. Targeted applications include battery
powered equipment that benefit from the devices’ low power
consumption (5µW), low leakage currents (3nA 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 device may be used to “mux-in” additional
functionality while reducing ASIC design risk. It’s small
package alleviates board space limitations, making it an ideal
solution.
The ISL43210 is a single committed SPDT, which is perfect
for use in 2-to-1 multiplexer applications.
