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

The ISL84541 is a precision, dual analog switch designed to operate from a single +2.7V to +12V supply. Targeted applications include battery-powered equipment that benefits from the devices' low power consumption (5µW), low leakage currents (100pA max), and fast switching speeds (tON = 35ns, tOFF = 25ns). 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. The ISL84541 is a dual single-pole single-throw (SPST) device. The ISL84541 has two normally open (NO) switches.
