Low-Voltage, Single Supply, Dual SPST, SPDT Analog Switches

The Intersil ISL43120, ISL43121, ISL43122 and ISL43210 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’ low power consumption (5μW), low leakage currents (100pA max), and fast switching speeds (tON = 28ns, tOFF = 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 “mux-in” additional functionality while reducing ASIC design risk. Some of the smallest packages are available, alleviating board space limitations, and making Intersil’s newest line of low-voltage switches an ideal solution.
