ISL84684
Ultra Low ON-Resistance, Low Voltage, Single Supply, Dual SPDT Analog Switch
FN6088 Rev 5.00 July 31, 2007
The Intersil ISL84684 device is a low ON-resistance, low voltage, bidirectional, dual single-pole/double-throw (SPDT) analog switch designed to operate from a single +1.65V to +3.6V supply. Targeted applications include battery powered equipment that benefits from low rON (0.35 and fast switching speeds (tON = 50ns, tOFF = 27ns). The digital logic input is 1.8V logic-compatible when using a single +3V supply.
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.
