Low-Voltage, Single and Dual Supply, Quad SPST, Analog Switches

The Intersil ISL84521, ISL84523, ISL84523 devices are CMOS, precision, quad analog switches designed to operate from a single +2V to +12V supply or from a ±2V to ±6V supply. Targeted applications include battery powered equipment that benefit from the devices’ low power consumption (<1μW), low leakage currents (1nA max), and fast switching speeds (tON = 45ns, tOFF = 15ns). A12Ω maximum RON flatness ensures signal fidelity, while channel-to-channel mismatch is guaranteed to be less than 4Ω.
