General Description
MAX4668 General Description
The MAX4667/MAX4668/MAX4669 dual analog switches feature low on-resistance of 2.5½ max. On-resistance is matched between switches to 0.5½ max and is flat (0.5½ max) over the specified signal range. Each switch can handle Rail-to-Rail® analog signals. The off-leakage current is only 5nA max at +85°C. These analog switches are ideal in low-distortion applications and are the preferred 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 supplies or a single +12V supply.
