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 (tON = 50ns, tOFF = 30ns). A 4Ω maximum RON flatness ensures signal fidelity, while channel to channel mismatch is guaranteed to be less than 2Ω. The ISL8394 is a quad single-pole/double-throw (SPDT) device and can be used as a quad SPDT, a quad 2:1 multiplexer, a single 4:1 multiplexer, or a dual 2-channel differential multiplexer.
