ISL8323, ISL8324, ISL8325
Low-Voltage, Single Supply, Dual SPST
Analog Switches
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 (5W), 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/single-
throw (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.
