Medium-Voltage, Single Supply, Single SPDT Analog
Switch
ISL43210A
Features
The Intersil ISL43210A device is a precision, bidirectional,
single SPDT analog switch designed to operate from a single
+2.7V to +15V supply. Targeted applications include

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.
