ISL8325 Low-Voltage, Single Supply, Dual SPST Analog Switches

The Intersil ISL8323,ISL8324,ISL8325 devices are precision, 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 (5uW), low leakage currents (100pA max), and fast switching speeds. Excellent RON matching and flatness maintain signal fidelity over the whole input range.

The ISL8323/ISL8324/ISL8325 are dual single-pole/singlethrow (SPST) devices. The ISL8323 has two normally open (NO) switches; the ISL8324 has two normally closed (NC) switches; the ISL8325 has one NO and one NC switch and can be used as an SPDT. Table 1 summarizes the performance of this family. For higher performance, pin compatible versions, or SOT-23 packaged devices, see the ISL5120-23 data sheet.
