Low-Voltage, Single and Dual Supply,
Quad SPDT, High Performance Analog
Switches
The Intersil ISL43240 device is a CMOS, 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 (5nA max), and fast switching speeds (t_ON = 52ns,
t_OFF = 40ns). A 5Ω maximum R_ON 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.
