Description

The MAX4601/MAX4602/MAX4603 quad analog switches feature low on-resistance of 2.5W max. On-resistance is matched between switches to 0.5W max and is flat (0.5W max) over the specified signal range. Each switch can handle Rail-to-Rail^® analog signals. The offleakage current is only 2.5nA maximum at TA = +85. The MAX4603 is 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, require less board space, and are more reliable than mechanical relays.

The MAX4601 has four normally closed (NC) switches, the MAX4602 has four normally open (NO) switches, and the MAX4603 has two NC and two NO switches. These switches operate from a single supply of +4.5V to +36V or from dual supplies of ±4.5V to ±20V. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using ±15V or a single +12V supply.
