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

   The Intersil ISL8394 device is a precision, quad SPDT 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 (5µW), low leakage currents (2.5nA max), and fast switching speeds (t ON = 50ns, tOFF = 30ns). A 4Ω maximum RON flatness ensures signal fidelity, while channel to channel mismatch is guaranteed to be less than 2Ω.
