The Intersil ISL8323–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 (5µW), low leakage currents (100pA max), and fast switching speeds. Excellent R_ON 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.
