 Description |
|
|
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 (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 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. |
