ISL43240

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

Product Status: 量産中(*)

OVERVIEW

The Intersil ISL43240 device is a CMOS, precision, quad SPDT analog switch 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 (5nA max), and fast switching speeds (tON = 52ns, tOFF = 40ns). A 5Ω maximum rON flatness ensures signal fidelity, while channel-to-channel mismatch is guaranteed to be less than 2Ω.

The ISL43240 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.Table 1 summarizes the performance of this family.
