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

The Intersil ISL43140–ISL43142 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 = 30ns, tOFF = 18ns). A 12Ω maximum RON flatness ensures signal fidelity, while channel-to-channel mismatch is guaranteed to be less than 2.5Ω. The 3mm x 3mm Quad No-Lead Flatpack (QFN) package alleviates board space limitations, making this newest line of low-voltage switches an ideal solution.
