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.
