2.5Ω, Dual, SPST,
CMOS Analog Switches
General Description
The MAX4667/MAX4668/MAX4669 dual analog switches
feature low on-resistance of 2.5Ω max. On-resistance is
matched between switches to 0.5Ω max and is flat (0.5Ω
max) over the specified signal range. Each switch can
handle Rail-to-Rail^® analog signals. The off-leakage cur-
rent is only 5nA max at +85°C. These analog switches
are ideal in low-distortion applications and are the pre-
ferred solution over mechanical relays in automatic test
equipment or applications where current switching is
required. They have low power requirements, use less
board space, and are more reliable than mechanical
relays.
The MAX4667 has two normally closed (NC) switches,
the MAX4668 has two normally open (NO) switches,
and the MAX4669 has one NC and one NO switch that
guarantee break-before-make operation.
These switches operate from a +4.5V to +36V single
supply or from ±4.5V to ±20V dual supplies. All digital
inputs have +0.8V and +2.4V logic thresholds, ensuring
TTL/CMOS-logic compatibility when using ±15V sup-
plies or a single +12V supply.
